The correct option is A Qutub ud din Aibak
Qutub Minar was built in 1193 by Qutab-ud-din Aibak immediately after the defeat of Delhi's last Hindu kingdom. He started construction of the Qutub Minar's first storey around 1192 which was later completed by Iltutmish. The conical tower is an exquisite example of Indo-Islamic Afghan architecture.
