Match List I with List II and select the correct answer:

List I	List II
a. Republic	1. Head of the State is not a hereditary monarch
b. Secular	2. State does not recognize any religion as a state religion
c. Democracy	3. A form of government which gets its authority from the will of the people

First, let's define the key terms:
Republic: A republic is a form of government where the head of state is not a hereditary monarch (i.e., not a king or queen who inherits the position). The power rests with the elected representatives of the people.

Secular: A secular state is one that does not officially endorse or favor any particular religion. It maintains neutrality in religious matters and ensures equal rights for all religions.

Democracy: A democracy is a system of government where supreme power is vested in the people and exercised directly by them or by their elected representatives under a free electoral system.

Now, let's match the terms in List I with their corresponding definitions in List II:

a. Republic - 1. Head of the State is not a hereditary monarch: This is a correct match. The definition of a republic directly states that the head of state is not a hereditary monarch.

b. Secular - 2. State does not recognize any religion as a state religion: This is also a correct match. A secular state's defining characteristic is its non-endorsement of any specific religion.

c. Democracy - 3. A form of government which gets its authority from the will of the people: This is the correct match. The definition accurately describes the core principle of democracy: that power originates from the consent of the governed.

Therefore, the correct answer is Option A: a-1, b-2, c-3
