Answer: Option 'd' is correct.
Explanation:
Since we have given that
Number of fish caught = 100
Number of tagged fish in catch = 24
So, total number of the fish in the pond is given by
Number of fish caught + Number of tagged fish in catch
=100 +24
= 124
So, the best estimate to find the number of fish in the pond is 124.
Hence, Option 'd' is correct.
