Answer : C

Given numbers: 4, 4, 5, 7, 6, 7, 7, 12, 3

To calculate the median, arrange the given data in ascending order and then find the middle term. This middle term is called the median.

Firstly, we will arrange the numbers in ascending order –

3, 4, 4, 5, 6, 7, 7, 7, 12

There are 9 number of observations.

For odd number of observations, middle term  

=\left ( \frac{n+1}{2} \right )^{th}\text {term}=\left ( \frac{9+1}{2} \right )^{th}\text {term}=\left ( \frac{10}{2} \right )^{th}\text {term}=5^{th}\text {term}

5th term is 6, hence it is the required median.

Therefore option (C) is correct.
