Means a resolution of 720 pixels across, displayed interlaced.

Explanation:
Interlaced video uses two fields to build a full frame, and the number in the label refers to the vertical resolution (the number of horizontal lines), not the width. So 720i means 720 lines of vertical resolution displayed with interlaced scanning. That matches the description of being interlaced and around 720 lines high. The other options describe either progressive scanning or different line counts: 720p is 720 lines but progressive; 1080i has 1080 lines interlaced; 480p has 480 lines progressive. Therefore, 720 interlaced is the correct match.
