Correct Answer: BVKRWMR

Solution : Given:
_VJRWB_ _RWBVL_ _BV_ _W

To fill the series we have to divide the series – _VJRW / B_ _RW / BVL_ _ / BV_ _W

Let's check each option –
First option: AVKRWMR ; A VJRW / B VK RW / BVL RW / BV MR W (No repeated pattern has been found)
Second option: AWKRXNR ; A VJRW / B WK RW / BVL RX / BV NR W (No repeated pattern has been found)
Third option: BVKRWMR ; B VJRW / B VK RW / BVL RW / BV MR W (The third letter in each part is increased by 1; The remaining letters BVRW is repeated in the series)
Fourth option: BWKRWMR ; B VJRW / B WK RW / BVL RW / BV MR W (No repeated pattern has been found)

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