If ‘SUMMER’ is coded as ‘RUNNER’, how will you code ‘WINTER’ ?

The correct answer is (c) WALKER.

The code is a simple substitution cipher, where each letter in the original word is replaced with the letter three places after it in the alphabet. For example, S becomes R, U becomes N, M becomes E, M becomes R, E becomes U, R becomes N, and so on.

Applying this cipher to the word “WINTER”, we get “WALKER”.

The other options are incorrect because they do not follow the same pattern. For example, “SUITER” is not a valid substitution cipher for “WINTER” because the letters S and U are not three places apart in the alphabet.
