The decimal number 1247 consists of the digits 1, 2, 4, and 7. We convert each digit to binary as follows:

- The digit 1 in binary is 0001.

- The digit 2 in binary is 0010.

- The digit 4 in binary is 0100.

- The digit 7 in binary is 0111.

2. 0010 (for 2)

3. 0100 (for 4)

4. 0111 (for 7)

Thus, the complete BCD representation of the decimal number 1247 is 0001 0010 0100 0111. This matches the first choice given.
