Answer 1

which

Step-by-step explanation:

The correct answer is "which." The phrase "all of which" is a relative pronoun that is used to refer back to the noun "computers" and indicate that all of them are old. So the correct sentence would be "Pamela has three computers, all of which are very old." The other options do not fit grammatically or semantically in the sentence.
