Select the triad that follows the same pattern as the one followed by the two triads given below. Both triads follow the same pattern.
FM-HO-JL
HO-JQ-LN

Given: 

FM-HO-JL
HO-JQ-LN

Logic: 1st letter + 2 = 3rd letter and 3rd letter + 2 = 5th letter

2nd letter + 2 = 4th letter and 4th letter - 3 = 6th letter

For, FM-HO-JL

F + 2 = H, H + 2 = J

M + 2 = O, O - 3 = L

For, HO-JQ-LN

H + 2 = J, J + 2 = L

O + 2 = Q, Q - 3 = N

Now, we check each options.

Option (a): LS-NU-PR (Follow)

L + 2 = N, N + 2 = P

S + 2 = U, U - 3 = R

Option (b): KS-NV-PQ (Not Follow)​

K + 2 $$\neq$$ N, N + 2 = P

S + 2 $$\neq$$ V, V - 3 $$\neq$$ Q​

Option (c): KS-NU-PQ (Not Follow)​

K + 2 $$\neq$$ N, N + 2 = P

S + 2 = U, U - 3 $$\neq$$ Q

Option (d): LS-NU-PS (Not Follow)​

L + 2 = N, N + 2 = P

S + 2 = U, U - 3 $$\neq$$ S

Thus, correct option is (a).
