III. 5,555,554,673
A. I only
B. I and II
C. II and III
D. II Only
E. I and III
Divisibility rule of 2: The number should be even or the last digit should be divisible by 2
Divisibility rule of 3: The sum of all the digits of the number should be divisible by 3
I. 234,124,422
Last digit -2. This is divisible by 2
Sum of digits = 24. This is divisible by 3
Hence the number is divisible by both 2 and 3
II. 88,865,544,264
Last digit -2. This is divisible by 2
Sum of digits = 60. This is divisible by 3
Hence the number is divisible by both 2 and 3
III. 5,555,554,673
Last digit - 3. This is not divisible by 2.
Hence only I and II are divisible by both 2 and 3
