The correct answer is c. whose. "Whose" is used to indicate possession or ownership.

To determine the correct answer, let's break down the sentence and analyze the usage of each option:

a. "who" is used as the subject of a sentence, for example, "Who is that person?"
b. "whom" is used as the object of a verb or a preposition, for example, "To whom should I address this letter?"
c. "whose" is used to indicate possession or ownership, for example, "Whose book is this?"
d. "who's" is a contraction of "who is" or "who has," for example, "Who's going to the party?"

In the given sentence, the word "from" indicates preposition, which makes "whom" the correct option. Therefore, the correct answer is option b. "whom." It would be "Can you remember the name of the person from whom you received this information?"
