Select the option that represents the letters that when placed from left to right in the blanks below will complete the letter series.
L_P_QS_K_P_S_KP_Q_L_ _PQS

Given: L_P_QS_K_P_S_KP_Q_L_ _PQS

Logic: We have to put each option in the blank space when any option gives us a proper logical series that will be correct option.

From option (a):KPLPQLPSKP

LKPPQS / LKPPQS / LKPPQS / LKPPQS (follows logical pattern)

From option (b):KPLPLQLSPK

LKPPQSLKPPLSQKPLQSLPKPQS (not follows logical pattern)

From option (c):KPLPQQLPSK

LKPPQSLKPPQSQKPLQPLSKPQS (not follows the logical pattern)

From option (d):PKLPQPLSKP

LPPKQSLKPPQSPKPLQSLKPPQS (not follows logical pattern)

Thus, option A is correct.
