Answer-If BOY is coded DQA, then how will CAT be coded?

To decipher the coding pattern, lets analyze the transformation from BOY to DQA B - D O - Q Y - A Looking at this transformation, it seems each letter is shifted by two positions in the alphabet, and the alphabets are wrapped around e.g., after Z comes A. Applying the same pattern to CAT C - E A - C T - V So, CAT would be coded as ECV using the same coding pattern.
