I guess A. Simple past is preferable over present continuous.

IMO B.

I was struggling between B and E ( both have correct verb form ). both increasing and increased are adjectives codifying difficulty.. but choose B for difficulty vs difficulties.
But, if option B were not there, I would have choosen E.. can somebody explain what is the problem with E ?

smell apears --> present tense.. so other part of the sentence should be in present tense too..

increased difficulty in homing vs increasing difficulties in homing.

B and E left.

increasing difficulties in homing --> distorts the meaning..
it means.. diffculties are increasing in homing (i.e initially birds have only two difficulties.. now increasing to 5 and then 10... ) -

obviously B is the best choice.

Has to be a present continuous.
I will go for B. "found to have increased difficulties in homing" distorts the meaning.
What is OA?

B remains. There is only one difficulty here. Difficulty in homing. No need for plural.

Do we need present continuous? I dont think so. But B seems to be the best answer.

There was a similar Q, which was tweaked by the OP to mirror this situation.

It appears that were found to have increased difficulty is a better choice , but as it is not one of the answer choice, I guess we need to pick B.

Can some one who has looked into this issue of not having a continuous tense any where in the original sentence, but answer appearing with continuous tense comment?

Since signals present perfect tense.. so have been is correct.
IMO B

A. were found to have increased difficulties
B. have been found to have increased difficulty
C. were found to have increasing difficulty
D. had been found to have increased difficulties
E. have been found to have increasing difficulties

the principal clause is in present tense. So we should look for present tense or present perfect tense.
So only B and D remain
In E increasing difficulties is wrong as the difficulties are not increasing continuously.
It should be increased difficulty.
