d.

Ramp

To determine which word has the same root as "diagram," you can break down the word and analyze its components. The root of "diagram" is "di-" which means "through" or "across."

Now, let's compare the other words:

a. "Agree" does not have the root "di-," so it is not the correct answer.

b. "Diameter" also contains the root "di-." The root in this case means "across" or "through" (specifically, "through the center"). Therefore, "diameter" has the same root as "diagram." The answer is b.

c. "Grade" does not contain the root "di-," so it is not the correct answer.

d. "Ramp" does not contain the root "di-," so it is not the correct answer.

Therefore, the word that has the same root as "diagram" is "diameter" (option b).
