Correct Answer: bpsgpcbp

Solution : Given:
g_c_p_c_b c_p s_g_c p_s c

To fill the series, we have to divide the series – g_c_p_c / _b c_p s_ / g_c p_s c
Let's check each option –
First option: bpsppsbp; g b c p p s c / p bc p ps s / g b cp p sc (No repeated pattern has been found.)
Second option: bpegpsbp; g b c p p e c / g bc p ps s / g b cp p c (No repeated pattern has been found.)
Third option: bpsgpcbp; g b c p p s c / gbc p ps c / g b cp p sc (gbcppsc is repeated in the series.)
Fourth option: bpspgcbp; g b c p p s c / p bc g ps c / g b cp p sc (No repeated pattern has been found.)

So, the series becomes→gbcppscgbcppscgbcppsc. Hence, the third option is correct.
