The correct answer is [B]

-The mean = 5.8
-The total sum of the numbers = 5.8 x 10 = 58
-The sum of the nine numbers
= 5 + 9 + 3 + 7 + 6 + 4 + 6 + 5 + 7 = 52
-The tenth number = 58-52 = 6
-Mode is the most repeated number = 6
-To get median arrange the numbers in ascending order then pick the middle number.
3, 4, 5, 5, 6, 6, 6, 7, 7 ,9
6, 6 are in the middle.

-Product of the mode and the medium = 6 x 6 = 36
