A linear drive converts _______________ motion into linear motion.

Explanation:
Linear drives are designed to turn rotational input into straight-line movement. In practice, a motor’s rotation is converted by mechanisms such as a lead screw, ball screw, or rack-and-pinion so that a nut or rack moves along a straight path. That clearly describes using rotary motion as the input to achieve linear motion, which is why rotary is the correct idea. Reciprocating or oscillating describe motion that is already back-and-forth or angular, not the conversion process from rotation to translation, and linear input would bypass the need for conversion.
