(a) TFUVSM 
(B) QGSTQM
(C) TGVWTP
(D) TGRVSO

Ans :- (c)

Solution :- As,   M      ⁺²       ► O
                          A       ⁺²       ► C
                          R      ⁺²       ► T
                          C      ⁺²       ► E
                          H      ⁺²       ► J

Similarly, 
                          R      ⁺²       ► T
                          E      ⁺²       ► G
                          T      ⁺²       ► V
                          U      ⁺²       ► W
                          R      ⁺²       ► T
                          N      ⁺²       ► P
