(B) that all older workers be retained by employers
(C) the retaining by employers of all older workers
(D) employers' retention of all older workers
(E) employers to retain all older workers

Guys ,

If i use command subjective then is option B right?

If i use Idiom the i think Option E follows

OAE

I want to know what's wrong with B .

Pls correct me.

B is incorrect because of parallelism there is no verb to match "show" in the left hand side of choice B

With B, the sentence would be:

Senator Lasker has proposed legislation requiring that all older workers be retained by employers indefinitely or show just cause for dismissal.

So, from a parallelism perspective, the structure is:

...all older workers:
i) be retained by employers indefinitely or
ii) show just cause for dismissal

So, this seems to suggest that the older workers are supposed to show just cause for dismissal!

As per original sentence, the employers are supposed to show just cause for dismissal.
