Answer 2

Answer:

Option D

Step-by-step explanation:

First we will try to divide 6912 by all the options, then we will get the answer.

(a) 2 and 3

As the digit in ones place is even, so it will be divisible by 2.

Now, we sum all the digits: 6+9+1+2= 18.

As 18 is divisible by 3, So option A is correct.

(b) 2 and 9

As we saw above, the last digit is 2 as it is an even number, the number 6912 is divisible by 2.

Now, 6912/9= 768. So, it is divisible by 9.

Hence, option B is also correct.

(c) 3 and 9

As we saw above that 6912 is divisible by 3 and 9,

So, option C is also correct.

(d) All of the above

As all of the options are correct, hence the correct answer is OPTION D.
