Question

she experimented with other fluids at home, she also asked her sons chemistry teacher for advice.
run - on sentence
comma splice
correct sentence

Explanation:

A comma splice occurs when two independent clauses are joined only by a comma. Here, "She experimented with other fluids at home" and "she also asked her son's chemistry teacher for advice" are independent clauses joined by just a comma. A run - on sentence combines two or more independent clauses without proper punctuation or conjunctions. This is specifically a comma splice rather than a general run - on. It is not a correct sentence.

Answer:

B. comma splice
