The auxiliary verb "Did" is already in the past tense. When "Did" is used, the main verb must be in its base form (infinitive without "to").
The correct verb form is:
"call" (base form of the verb).
The correct sentence should be:
"Did you call her yesterday?"
Thus, the correct answer is Option A ("call").
