Question

Correct — A, Jabalpur. Jabalpur lies at about 79.95° E, just west of the 80° E meridian, making it the closest of the four listed places to 80° E longitude. Panna, Katni and especially Rewa sit farther east of the 80° line, so Jabalpur is the nearest to it.

Why the other options are wrong — (b) Rewa lies well east of the 80° E meridian (around 81° E), so it is the farthest of the four from the 80° line.  (c) Panna lies east of 80° E, farther from the meridian than Jabalpur.  (d) Katni also lies east of 80° E; though close to Jabalpur, it is a little farther from the exact 80° line.

Concept: Longitudes are the north–south lines measured east or west of the Prime Meridian (0°). India lies between about 68° E and 97° E, and its Standard Meridian is 82.5° E (passing near Mirzapur, Uttar Pradesh), which fixes Indian Standard Time. Madhya Pradesh, in central India, is crossed by meridians in the high-70s to low-80s ° E, so the 80° E line runs through its eastern part.
