Critical Reasoning

Although the question has been already asked before on BTG(https://www.beatthegmat.com/1000-cr-test ... t1835.html), I am not convinced with the explanation and OA. I searched on the net, but all-in-vein. I don't know the OA too, so let's discuss.

In many surveys, American consumers have expressed a willingness to spend up to 10 percent more for products that are ecologically sound. Encouraged by such surveys, Bleach-O Corporation promoted a new laundry detergent, Bleach-O Green, as safer for the environment. Bleach-O Green cost 5 percent more than typical detergents. After one year, Bleach-O Green had failed to capture a significant share of the detergent market and was withdrawn from sale.

Which of the following questions is LEAST likely to be relevant in determining the reasons for the failure of Bleach-O Green?

(A) How effective as a detergent was Bleach-O Green?

(B) How many other detergents on the market were promoted as safe for the environment?

(C) How much more did Bleach-O Green cost to manufacture than ordinary detergents?

(D) To what extent did consumers accept the validity of Bleach-O Green advertised and promoted to consumers?

(E) How effectively was Bleach-O Green advertised and promoted to consumers?

(A) How effective as a detergent was Bleach-O Green? -> If Bleach Green is not effective as a detergent, then people will not buy and hence the failure. RELEVANT

(B) How many other detergents on the market were promoted as safe for the environment? -> If Bleach Green has competition then it is very much possible that Bleach could have lost out to a competitor. RELEVANT

(C) How much more did Bleach-O Green cost to manufacture than ordinary detergents? NOT RELEVANT

(D) To what extent did consumers accept the validity of Bleach-O Green advertised and promoted to consumers? If the consumers did not accept the concept of Bleach Green, then they will not buy and hence the failure. RELEVANT

(E) How effectively was Bleach-O Green advertised and promoted to consumers? If Bleach Green was not properly advertised, marketing failure could be attributed to the failure. RELEVANT

Good explanation snsubbu.

One more vote for C since we dont care how much it costs to make it. This has nothing to do with failure of the product among consumers/public.

We could be concerned about a few things namely:

1) Was it ecologically sound?
2) Was it effective as a detergent?
3) Did the customers believe the ad's(2 choices point to this)?
4) Were there others in the markest that were cheaper but were as effective as Bleach whetver?

I also selected C, but in the old post everyone agreed on B. That's why, I just wanted to ensure that I am not missing something.

Thanks

Eh...I was reading the answer explanation in the other thread and the explanation seems to support C????

Answer C seems to be logical one out of other answer choices
