The system will allocate 2 bytes for the union.
Correct Option: A
The system will allocate 2 bytes for the union.
First byte for ch[0] i.e. for 10 = 00001010
Second byte for ch[1] i.e. for 20 = 000010100
Combining these 2 we get 00001010 000010100 which is equivalent to 5130 in decimal.
So answer will be 10 20 5130
