A. 1100010_{2}

B. 110110_{2}

C. 1100011_{2}

D. 1101101_{2}

### Check Answer

The correct answer is

To convert an octal number to a binary number, we need to convert each digit of the octal number to a three-digit binary number.

In this case, the octal number is 1428. To convert it to binary, we can convert each octal digit as follows:

1 → 001 4 → 100 2 → 010

So, the binary equivalent of 1428 is 001 100 010, which when combined is 1100010.

Therefore, the correct answer is A) 1100010 2.
