Question #N857

The famous scientist Albert Einstein, who developed the theory of relativity, is known for his iconic equation: E=mc^2.

Which choice most effectively combines the sentences above into a single, grammatically correct sentence?
A. The famous scientist Albert Einstein who developed the theory of relativity, is known for his iconic equation: E=mc^2.
B. The famous scientist Albert Einstein, who developed the theory of relativity, is known for his iconic equation: E=mc^2.
C. The famous scientist Albert Einstein, who developed the theory of relativity, known for his iconic equation: E=mc^2.
D. The famous scientist Albert Einstein, who developed the theory of relativity, known for his iconic equation, E=mc^2.

Correct Answer is: B

Choice B is the most effective way to combine the sentences because it uses a comma to separate the introductory phrase "who developed the theory of relativity" from the main clause and uses a comma to separate the nonessential phrase "E=mc^2" from the rest of the sentence. This is the most conventional and grammatically correct way to join the sentences.
