The Correct Option is D
Solution and Explanation
By using permutation and Combination,
we can get the No. of ways our men can sit on left side = 3C2 * 4! – Equation 1
and No. of ways our men can sit on right side = 4! – Equation 2
Total ways = By multiplying the equation 1 and equation 2
= 3C2*4!*4!
= 1728
The correct option is (D)
