The Anchuthengu Fort was established by the British East India Company on land leased from:

The correct answer is: A) Cochin.

The Anchuthengu Fort was established by the British East India Company in 1696 on land leased from the Raja of Cochin. The fort was built to protect the British trade interests in the region and to prevent the Dutch from expanding their influence. The fort was also used as a base for British troops during the Anglo-Mysore Wars.

The other options are incorrect because:

• Option B, Travancore, was a princely state in India that was not under the control of the British East India Company.
• Option C, Attingal, was a small kingdom that was also not under the control of the British East India Company.
• Option D, Kollam, was a port city that was under the control of the Dutch East India Company.

The Anchuthengu Fort is a well-preserved example of 17th-century military architecture. The fort is rectangular in shape and is surrounded by a moat and a wall. The fort has four bastions and a central keep. The fort is now a museum and is open to the public.
