@Teja:.
Converting to Hexadecimal is unnecessary. It can be directly converted to binary without converting to hexadecimal.
However, the question asked for the BCD code, not the binary equivalent of the decimal number. So the answer should be B.

Correct Answer is A.
They asked for BCD not to convert in Hexadecimal.
BCD is having 0 to 9 range only.
That's why 0 - 0000 and 9 - 1001.
So, as per questin value, 125- 0001 0010 0101.

125 is a decimal number.
Convert it to a hexadecimal number (7D).
Then plot binary of 8421=1111101.
So option [A] is correct.

The answer should be B, ex BCD is nothing but 4bits binary number so 125 =0001 0010 0101.
