Jalen says that the difference between the greatest length and the least length is 2 inches. Is Jalen correct? Explain your reasoning.
A. Jalen is correct. The greatest length has 4 dots and the least length has 2 dots, so the difference is 2 inches.
B. Jalen is not correct. The greatest length has 6 dots and the least length has 1 dot, so the difference is 5 inches.
C. Jalen is not correct. The greatest length is 1 4/8 inches and the least length is 3/8 inch, so the difference is 1 1/8 inches.
D. Jalen is not correct. The greatest length is 1 inch and the least length is 7/8 inch, so the difference is 1/8 inch.
