The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic people has been established by carbon-14 dating, but what is much more difficult to determine are the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals.

(A) has been established by carbon-14 dating, but what is much more difficult to determine are
(B) has been established by carbon-14 dating, but what is much more difficult to determine is

I will go with A as the last part of sentence is a compound subject ("the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals").

"reason" is not a subject and getting qualified by the remainder of the sentence. Subject is rather a combination of "the reason for their decoration", "the use to which primitive people put the caves" and "the meaning of the magnificently depicted animals".

i.e. the subject is a combination of reason......, use...... and meaning.

Awaiting OA.

"is" is required at the end of underlined part A and D out....the period is singular...C and E out,

therefore IMO B

OA is B

try to find the subject of the sentence.

Here subject is clause "what is much more difficult to determine "
clause is singlular when it is subject of another clause.
