Final answer:
The largest email is 3,000 times greater than the smallest email.
Step-by-step explanation:
To find the number of times the largest email is greater than the smallest email, divide the largest email by the smallest email.
Let's say the largest email is 6,000 and the smallest email is 2.
To find the number of times the largest email is greater than the smallest email, divide 6,000 by 2:
6,000 รท 2 = 3,000.
Therefore, the largest email is 3,000 times greater than the smallest email. So the answer is option C. 3,000.
