Answer 1

Hint: This invader vowed to invade India once a year and was quite successful for an extended time. He started his invasions in 1001 and died in 1030.

Complete solution: Mahmood Gaznavi was born in 971 AD, in Khurasan. In 994 Mahmood joined his father within the conquest of Ghazni for Samanid ruler, it had been the time of instability for the Samanid Empire.
Moving further in his life timeline, we see that in 1001 AD, he started his military companies, which lasted before his death in 1030 AD. Mahmood of Ghazna was one of the undefeatable military commanders of the earth .
He attacked South Asia seventeen times successfully and went back to Ghazni whenever with a superb victory. He is said to have vowed to invade India once a year and, in fact, led about 17 such expeditions. The primary large-scale campaign began in 1001 and thus the last led to 1026. the primary expeditions were aimed against the Punjab and northeastern India, whereas in his last campaign Mahmud reached Somnath on the southern coast of what is now Gujarat state With this explanation, it's made clear to us that he invaded India 17 times during a span of 25 years, hence option d is that the correct answer.

Note: This person is the first in history to assume the title of Sultan, he did so because he established the Ghaznavid empire. He invaded India to increase his territory further.
