Correct Answer: LBEUHPS

Solution : Given:
BUP_ESH_UPL_SHB_PLES_BU_LE_H

To fill the series we have to divide the series – BUP_ESH / _UPL_SH / B_PLES_ / BU_LE_H

Let's check each option –
First option : LBEHUSP; BUP L ESH / B UPL E SH / B H PLES U / BU S LE P H (No repeated pattern has been found.)
Second option: LBEUHPS; BUP L ESH / B UPL E SH / B U PLES H / BU P LE S H (BUPLESH is repeated in the series.)
Third option: LBEUPSH; BUP L ESH / B UPL E SH / B U PLES P / BU S LE H H (No repeated pattern has been found.)
Fourth option: LBEPUSH; BUP L ESH / B UPL E SH / B P PLES U / BU S LE H H (No repeated pattern has been found.)

So, the series becomes→BUPLESHBUPLESHBUPLESHBUPLESH. Hence, the second option is correct.
