I think to try and recover is not correct idiomatically.

To try and(conjunction) ... .... try what ? .. Seems incomplete.

To try to recover ... clearly specifies the intended meaning ...

the idiom is "to try to do" not try for doing or try and do

but why C and E are wrong?

Trying to recover uranium out of seawater may someday be worthwhile

You recover from something, not out of something

Recovering uranium from seawater may be worthwhile to try to do someday

to try to do is wrong and wordy.

It should have been:
Recovering uranium from seawater may be worthwhile to try someday

IMO : A
TO TRY TO DO is the correct idiom.
C is wrong because in the portion 'but at present this process is prohibitively expensive' this process is referring to 'Trying to recover uranium out of seawater' whereas the process is simply 'to recover uranium from seawater'

C, D and E are all passive

oa is A

why C and E is wrong?

Answer will be A.

C sounds passive and E sounds ackward ( to try to do someday)

have you ever heard that we should avoid to use"to do" and " doing" as subject

I hear this and this is why C and E is wrong

any idea, pls, speak up
