Critical Reasoning

According to advertisements, the higher a suntan lotion's sun protection factor, or SPF, the more protection from sunburn . In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter hat SPF a suntan lotion has.

Which one of the following best identifies the error in reasoning made in the passage?
(A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn.
(B) Because some people get sunburned more easily than others, the fact that there are different SPFs cannot be ignored.
(C) It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion.
(D) It is unreasonable to assume that all suntan lotions require the same application
(E) There is no reason to assume that manufacturer are unaware that people sometimes forget to apply suntan lotion before going in the sun.

Conclusion : Therefore, it really does not matter hat SPF a suntan lotion has.

Premise : one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed

We are basically being asked to find the flaw, or in other words we can find the flawed assumption

Assumption of the above argument is therefore that
SPF is not important because there are requirements for the application of the suntan lotion.

Which is the same as C
