Answer

the Government is responsible to the Parliament and can be removed by it

(b) Correct. In a parliamentary system, the executive is collectively responsible to the legislature and can be removed through a no-confidence motion.
(c) Incorrect. This describes neither the core feature of parliamentary government nor the Indian model; the government is not directly elected as an executive by the people.
(d) Incorrect. This is closer to a presidential system, where the executive has a fixed tenure and is not removable by the legislature through ordinary loss of confidence.
