**A. Answer: (4) gu.**

**Explanation:-**

a + 2 = c and r + 1 = s,

c + 2 = e and s + 1 = t,

e + 2 = g and t + 1 = u

Hence, the answer is gu.

**B. Answer: (4) 45**

**Explanation:-**

9 + 6 = 15, 15 + (6 + 2) = 23, 23 + (8 +2) = 33 in the same order 33 + (10 + 2) = 45.

Hence, the answer is (4) 45.

**C. Answer: (1) 481.**

**Explanation:-**

5 x 3 + 1 = 16, 16 x 3 + 3 = 51, 51 x 3 + 5 = 158

Similarly,

158 x 3 + 7 = 481.

Hence, the answer is (1) 481.

**D. Answer: (1) EDCBA.**

**E. Answer: (3) WX**

**Explanation:-**

A + 4 = E and D + 5 = I

E + 5 = J and I + 5 = N

J + 6 = P and N + 5 = S

P + 7 = W and S + 5 = X

Hence, the answer is (3) WX.

**F. Answer: (3) XWV.**

**Explanation:-**

P + 2 = R, R + 2 = T, T + 2 = V, Similarly, V + 2 = X

O + 2 = Q, Q + 2 = S, S + 2 = U, U + 2 = W

N + 2 = P, P + 2 = R, R + 2 = T, T + 2 = V

Hence, the answer is (3) XWV.
