Meteorologists study changes in Earth's atmosphere, they also forecast the weather. can some one help me plz

Answer 1

I qould say the awnser is B because of correct spelling and how it is writen with punctuation and word form

Answer 2

I'd say the correct answer is C. Because a compound sentence consists of at least two independent clauses, therefor A and B cannot be correct, because there is only one independent clause. D is also incorrect, because 'and' is redundant, it is not needed in this sentence. Therefore, you are left with C only.
