Correct Answer: Option C

Explanation

To find \( 110111_2 + 10100_2 \):

Convert to decimal: \(110111_2 = 55_{10}, \quad 10100_2 = 20_{10}\)

Add: \(55 + 20 = 75\)

Convert back to binary: \(75_{10} = 1001011_2\)

Final result: \(110111_2 + 10100_2 = 1001011_2\)

OR
\(\begin{array}{r}
  110111_2 \\
+ 010100_2 \\
\hline
 1001011_2
\end{array}\)

\(\therefore \; 110111_2 + 10100_2 = 1001011_2\)
