Best answer
Correct Answer - Option 3 : 360

Given:

The word is 'LEADER'.

Calculation:

The number of letter in LEADER = 6

The number of times letter E is present = 2

The total number of ways = 6!/2!

The total number of ways = 6 × 5 × 4 × 3 × 2 × 1/2 × 1 = 360

∴ The total number of ways is 360.
