• A. 84
• B. 56
• C. 94
• D. 76

Hint:

For such questions, check basic divisibility, odd/even properties, or factors first.

Answer 1

The Correct Option is C

Step 1: Find a common property.
Check divisibility:
\[ 84 \div 4 = 21, \quad 76 \div 4 = 19, \quad 56 \div 4 = 14, \quad 24 \div 4 = 6 \] All divisible by 4. \[ 94 \div 4 = 23.5 \] Not divisible by 4.
Step 2: Conclusion.
Thus, 94 is different.
