Method to Solve :
Numbers obtained in three throws are 6, 5 and 4.
Let the number obtained in fourth throw be x.
Now, Sum > 20
6 + 5 + 4 + x > 20
15 + x > 20
x > 20 – 15
x > 5
He must get a 6 in the fourth throw to win the game.
Let the number obtained in fourth throw be x.
Now, Sum > 20
6 + 5 + 4 + x > 20
15 + x > 20
x > 20 – 15
x > 5
He must get a 6 in the fourth throw to win the game.

Explanation:
In order to win the TV, the person needs to get a sum greater than 20 in four throws of a dice.
The person has already made three throws and obtained the numbers 5, 3, and 6. Now, we need to determine the number that should be thrown in the fourth attempt to win the TV.
Sum of the three throws:
5 + 3 + 6 = 14
Remaining sum needed to win the TV:
20 - 14 = 6
In order to win the TV, the person needs to get a sum greater than 20. However, the maximum number that can be obtained on a single throw of a dice is 6.
Maximum sum possible on the fourth throw:
6 (maximum value from a dice)
Even if the person gets the maximum value of 6 on the fourth throw, the total sum would be 14 + 6 = 20, which is not greater than 20. Therefore, it is not possible for the person to win the TV.
Conclusion:
The correct answer is option 'B' - the person never wins the TV.
