The correct answer is A. 110, 25.
The total number of seats in the UT of Jammu and Kashmir is 110, out of which 25 seats shall remain vacant for the Pakistan Occupied Kashmir (POK). This is because the POK is a disputed territory and India does not have control over it. The 25 seats that are reserved for the POK are not filled in the elections to the Jammu and Kashmir Legislative Assembly.
Option B is incorrect because it states that the total number of seats in the UT of Jammu and Kashmir is 107. This is not correct because the total number of seats is 110.
Option C is incorrect because it states that the total number of seats in the UT of Jammu and Kashmir is 120. This is not correct because the total number of seats is 110.
Option D is incorrect because it states that the total number of seats in the UT of Jammu and Kashmir is 110, out of which 27 seats shall remain vacant for the Pakistan Occupied Kashmir (POK). This is not correct because the number of seats that are reserved for the POK is 25, not 27.
