Tropical cyclones (hurricanes, typhoons, and cyclones) are systems of intense low pressure that develop under specific atmospheric and oceanic conditions.
Study the map below, which shows the track, central atmospheric pressure (in hectopascals, hPa\text{hPa}hPa), and maximum sustained wind speeds (in km/h\text{km/h}km/h) of Cyclone Marele in the South Indian Ocean.

Identify which one of the following dates recorded the deepest atmospheric depression (lowest central pressure) and peak storm intensity.
12 March
14 March
15 March
17 March
