Excess-3 BCD code is a self-complementary code, which means that the 10's complement of a number is obtained by flipping all the bits. It is also called XS-3 code or Stibitz code.

To represent the quantity 837 in excess-3 BCD code, we need to convert it into BCD first.

- Step 1: Convert 837 into binary

837 = 512 + 256 + 64 + 4 + 1 = 1101001101 (in binary)

- Step 2: Convert binary into BCD

1101 0011 0111 (in BCD)

- Step 3: Add 0011 (decimal 3 in excess-3 code) to each BCD digit

1101 0110 1010 (in excess-3 BCD)

Therefore, the quantity 837 in excess-3 BCD code would be represented as 1011 0110 1010.

We have to go from right to left , so first I check B having code 1011= 1×2^0 + 1×2^1 + 0×2^2 + 1×2^3 = 11 so, option C is correct.
