Explanation:

Correct option 1:6

Let’s observe the pattern of the last few digits of powers of 225:

• 225¹=225

• 225²=50625

• 225³=11390625

• 225⁴=2562890625

• .......

From this pattern, it becomes clear:

• All powers of 225 end with 625 starting from n=2

• So, 225⁴⁰ will end with ...625

So, the units place is 5
Tens place is 2
Hundreds place is 6

So, answer is 6.
