Correct Answer: RTSQ


Solution : Given:
QST _ QS _ RQ _ TR _STR

To fill the series we have to divide the series – QST _ / QS _ R / Q _ TR / _STR
Let's check each option –
First option: SQTR; QSTS / QSQR / QTTR / RSTR (No repeated pattern has been found)
Second option: RTSQ; QSTR / QSTR / QSTR / QSTR (QSTR is repeated in the series)
Third option: TRQS; QSTT / QSRR / QQTR / SSTR (No repeated pattern has been found)
Fourth option: TSRQ; QSTT / QSSR / QRTR /QSTR (No repeated pattern has been found)

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