Solution

To encrypt the message "VA" using the function f(p) = (p + 7) mod 26, follow these steps:

  1. Convert each letter in the message to its corresponding numerical value in the alphabet. In this case, V is 22 and A is 1.

  2. Apply the function f(p) = (p + 7) mod 26 to each numerical value. This means you add 7 to each value and then find the remainder when divided by 26.

    For V (22), (22 + 7) mod 26 = 29 mod 26 = 3.

    For A (1), (1 + 7) mod 26 = 8 mod 26 = 8.

  3. Convert these new numerical values back to letters. 3 corresponds to C and 8 corresponds to H.

So, the encrypted message is "CH". Therefore, the answer is b. CH.
