Correct Answer - Option 4 : 205.16.39.44

__Answer__: Option 4

__Explanation__:

Given first address: 205.16.32.0

Supernet mask: 255.255.248.0

__Option 1__: 205.16.42.56

performing bitwise and operation with supernet mask

11001101.00010000.00101010.00111000

11111111 .11111111 . 11111000 .00000000

-----------------------------------------------------------

11001101.00010000.00101000. 00000000

≡ 205.16.40.0 ≠ 205.16.32.0

Hence this is** not the correct** Option.

__Option 2__: 205.17.32.76

performing bitwise and operation with supernet mask

11001101.00010001.00100000.01001100

11111111 .11111111 . 11111000 .00000000

-----------------------------------------------------------

11001101.00010001.00100000. 00000000

≡ 205.17.32.0 ≠ 205.16.32.0

Hence this is not the correct Option.

__Option 3__: 205.16.31.10

performing bitwise and operation with supernet mask

11001101.00010000.00011111.00001010

11111111 .11111111 . 11111000 .00000000

-----------------------------------------------------------

11001101.00010000.00011000. 00000000

≡ 205.16.24.0 ≠ 205.16.32.0

Hence this is not the correct Option.

__Option 4__: 205.16.39.44

performing bitwise and operation with supernet mask

11001101.00010000.00100111.00101100

11111111 .11111111 . 11111000 .00000000

-----------------------------------------------------------

11001101.00010000.00010000. 00000000

≡ 205.16.32.0 == 205.16.32.0

Hence this is the correct Option.
