  2. It looks for the first abc string in the first 3 lines and replaces to xyz.

  3. It looks for the first abc string in line 3 and replaces to xyz.

C Correct answer
Explanation

The vi command ':3 s/abc/xyz/' means: on line 3, substitute (s) the first occurrence of 'abc' with 'xyz'. The '3' before s specifies the line number. Without the 'g' flag, only the first match is replaced. Option A is wrong (no global flag). Option B is wrong (only line 3, not first 3 lines). Option D is wrong (line 3, not first 3 matches).
