The correct answer is option 4, Colachel. In the battle of Colachel, Marthanda Varma, the ruler of the princely state of Travancore, defeated the Dutch East India Company in 1741.

Option 1, Wandiwash, is not the correct answer. The Battle of Wandiwash took place in 1760 between the British East India Company and the French East India Company.

Option 2, Rakshasi-Tangadi, is not the correct answer. There is no historical record or battle by this name involving the Dutch and Marthanda Varma.

Option 3, Pullalur, is not the correct answer. There is no recorded battle between the Dutch and Marthanda Varma at Pullalur.

It is worth noting that the defeat of the Dutch by Marthanda Varma at the Battle of Colachel was significant because it marked the first time an Asian power had successfully defeated a European colonial power. This victory solidified Marthanda Varma`s reign and established Travancore as a major power in the region.
