To find the position of Q in the row from the right, we need to analyze the given information step by step:

Step 1: P is standing at the 11th position from the left.
- This means that there are 10 people standing to the left of P.

Step 2: There are twelve people standing between P and Q.
- This means that there are 12 people standing between P and Q.

Step 3: The number of persons standing in the row is thrice the number of persons standing to the left of P.
- This means that the total number of people in the row is 3 times the number of people to the left of P.
- Since there are 10 people to the left of P, the total number of people in the row is 3 * 10 = 30.

Step 4: Finding the position of Q from the right.
- Since there are 30 people in the row, the position of Q from the right can be found by subtracting the position of P from the total number of people in the row.
- Position of Q from the right = Total number of people in the row - Position of P
- Position of Q from the right = 30 - 11
- Position of Q from the right = 19.

Therefore, the position of Q in the row from the right is 19th.

Hence, the correct answer is option C) 7th.

Number of people standing to the left of P = 11 - 1 = 10
Total number of people in the row = 10 × 3 = 30
Position of Q from left = 11 + 12 + 1 = 24rd
Position of Q from right = 30 - 24 + 1 = 7th
