Question

we can prove that the Earth is round. underline the principal clause​

Answer 1

Answer:

A Complex Sentence consists of one principal clause and any number of subordinate clauses.

A Noun Clause is a subordinate clause which does the work of a noun in a complex sentence.

In this case,

Option C is correct. The subordinate clause That the Earth is round acts as the subject of the verb is known in the principal clause. The subject is always either a noun or a pronoun. Henceforth, That the Earth is round is a subordinate noun clause as it behaves as a noun.

Option A is incorrect as the sentences have been joined by a subordinate adjective clause where the noun The Earth is being described.

Option B is incorrect as the sentences have been joined by a subordinate adverb clause which modifies the verb 'knows' in the principal clause.

Option D is incorrect as it's a simple

sentence.
