The correct option is A True
A compound sentence is made up of independent clauses that can stand on
their own as sentences. illative compound sentences contain independent
clauses, where one of them is inferred or concluded from the other. We're given two sentences, one of them "I plan on skipping work today," is concluded from the other, "It has been raining since last night.". Hence, an illative conjunction is essential to combine them effectively. "Therefore" is the appropriate illative conjunction, resulting in the given compound sentence. To conclude, the given compound sentence is the correct form of the individual sentences. Hence option A is correct and B is wrong. Option C is incorrect because a statement cannot be true as well as false. Option D is incorrect because the answer lies in A.
