It's B

The period when the great painted caves at Lascaux and Altamira were occupied the Upper Palcolithic people has been established (the period) by carbon-14 dating, but what is much more difficult to determine is (as you can see the reason is singular, so "is" is correct) the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals

Subject - primitive people Verb put the

“the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals” This long list of three factors is a compound noun, which acts as the object of the second clause

We can reverse a clause and bring in the object s the subject, provided what is before the verb cannot function as a subject in the text, say something like a prepositional phrase. Here, in this case, the noun phrases ‘what is more difficult to determine” can be a legal subject. Therefore ‘the reason’ cannot be preferred as the subject, by resorting to unnecessary reversal.

Missing "by" before "the Upper Palcolithic people". Please, take caution when posting.

Agree with aquarius24.....
Options with "have" can been eliminated directly....and sentence should be end with "is" not "are"...so Option B will be correct.

What is most important here is the identification of the Subject and the verb in the sentence and most importantly the subject in the sentence.

Thanks

Also, one thing to be noted in the above question is that all the 5 options use the noun phrase and noun phrase is singular.

However, if one of the options would have been 'to determine', then that would have been the correct answer and the plural verb 'are' would have been taken as the correct answer choice.

Hence singular verb and not a plural verb in the second clause of the sentence.

Thanks!!!

IMO: B is correct.

The period........ has ==> only B is correct.
Also, correct use of parallel structure: "what is much more difficult to determine is"

Hope it's clear.
