The correct answer is: A) Unicameral
A unicameral legislature is a legislature with only one chamber or house. The Karnataka State Legislature is a unicameral legislature, consisting of the Legislative Assembly. The Legislative Assembly has 225 members, who are elected from single-member constituencies by the people of Karnataka. The term of the Legislative Assembly is five years.
A bicameral legislature is a legislature with two chambers or houses. The two chambers are usually called the upper house and the lower house. The upper house is usually smaller than the lower house, and its members are often elected by indirect election. The lower house is usually larger than the upper house, and its members are usually elected by direct election.
A tricameral legislature is a legislature with three chambers or houses. The three chambers are usually called the upper house, the middle house, and the lower house. The upper house is usually the smallest chamber, and its members are often elected by indirect election. The middle house is usually the second-largest chamber, and its members are often elected by indirect election. The lower house is usually the largest chamber, and its members are usually elected by direct election.
None of the above is the correct answer because the Karnataka State Legislature is a unicameral legislature.
