She is ____ the software interface after using it for weeks.

She is ____ the software interface after using it for weeks.

• A. familiar with
• B. capable of
• C. in contrast to
• D. puzzled/confused/perplexed by

Answer: (A)

Gaining familiarity through experience is what this sentence needs to express. After weeks of using the software, she knows the interface well, so she is familiar with it. "Familiar with" is the natural complement here because it describes being acquainted with something through exposure. The other options do not convey that sense: "capable of" points to ability rather than knowledge; "in contrast to" is a comparison phrase, not a property of someone; "puzzled by" describes confusion, which contradicts becoming familiar. Thus, the best choice is the phrase that expresses earned familiarity.
