Which of the following is true whether you use a direct quote or an indirect quote?

The only true whether to use a direct quote or an indirect quote is that ‘You must use quotation marks to indicate the evidence.’ The answer is letter A.

"You must use quotation marks to indicate the evidence." 
indirect quotes don't have quotation marks...
direct quotes do. 
A is wrong.

"You must use an internal citation to indicate the source."
with everything you get your source from, always use internal citation, even if it's a direct or indirect quote. B is correct.

"You must use the exact words even with any of its errors." 
this only applies for direct quote, not indirect quotation. C is incorrect.

"You must use a capital letter at the beginning of the quote."
only for direct quotes, because that's a q-u-o-t-e. indirect quotes are your words, and at every sentence you start a new capital letter so D is incorrect.

Bis the correct sentence because saying he'd never then a past verb is grammatically wrong
