Solution:

(2)

The answer will be "(a) 131.107.256.80"

(a)

Given,

=>IP address = 131.107.256.80

Explanation:

=>IP address is of 32 bits, each octet contains 8 bits.

=>8 bits values can be from 00000000(0) to 11111111(255).

=>So range of each octet = [0, 255]

=>In the given IP address third octet value is 256 hence it is not a valid IP address.

(b)

Given,

=>IP address = 222.222.255.222

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address.

(c)

Given,

=>IP address = 231.200.1.1

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address.

(d)

Given,

=>IP address = 126.1.0.0

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address.

(e)

Given,

=>IP address = 0.127.4.100

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address.

(f)

Given,

=>IP address = 190.7.2.0

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address.

(g)

Given,

=>IP address = 127.1.1.1

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address

(h)

Given,

=>IP address = 198.121.254.255

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address

(i)

Given,

=>IP address = 255.255.255.255

Explanation:

=>In the given IP address all the octet's value come in the range [0, 255] hence the given IP address is a valid IP address

I have explained each and every part with the help of statements attached to it.
