Explanation
All operations given in the above options are simply arithmetic operations in the hexadecimal number system. We can perform this operation in multiple ways, i.e., we can either SUBTRACT them directly in hex or we can convert them to binary and then perform the operation and convert the result into hexadecimal again.
Use the following table for conversion:
In option 2, we have 14E = 000 10100 1110 and 7A = 00000 111 1010
14E - 7A = 000101001110 - 000001111010 = 000011010100
000011010100 = D4
Therefore, (14E) - (7A) (𝐷4) 16 16 = 16
