Answer:
A, 2500 cats
Step-by-step explanation
If the largest group has 502 cats, and the numbers are in sequence then the second group will be 502 -1 = 501 .
the third group will be 501- 1=
500
The fourth group will be 500 -1= 499
And the last group will be 499- 1= 498
There fore the total number of cats in the study is
502 + 501 + 500 + 499 + 498 = 2500
