The Correct Option is D

Solution and Explanation

Concept: Days repeat every 7 days, so we use modulo: \[ {Day after } n { days} = n \bmod 7 \]
Step 1: Find remainder.
\[ 200 \div 7 = 28 { remainder } 4 \]
Step 2: Count 4 days from Sunday.
\[ {Sunday} \rightarrow {Monday (1)} \rightarrow {Tuesday (2)} \rightarrow {Wednesday (3)} \rightarrow {Thursday (4)} \]
Hence, the day will be Thursday.
