B. that Earth
C. moves
D. round
E. the sun

Choose the correct answer from the options given below:

B only

The correct answer is Option (1) - B only

The sentence is:

"Copernicus proved that Earth moves round the sun."

Let’s check each part:

A. Copernicus proved → Correct.
B. that Earth → Incorrect, because "the Earth" should be used (Earth here is treated as a proper noun but with the definite article when talking about the planet in astronomy).
C. moves → Correct, present tense is fine since it’s a universal truth.
D. round → Correct, means "around."
E. the sun → Correct.

✅ Error is in B only.

Correct Sentence:
Copernicus proved that the Earth moves round the sun.
