which is the best way to revise this sentence?

Explanation:

In sentence revision for correct punctuation, non - restrictive relative clauses (like "who teaches biology" here) should be set off with commas. The first option misses the second comma after "biology", the third and fourth options have incorrect comma placements (unnecessary commas after "because"). Only the second option correctly uses commas to set off the non - restrictive clause.

Answer:

B. Eliana Rodriguez, who teaches biology, is my favorite teacher because she gives engaging lectures
