Answer

C. The invention of the world wide web, which was created by Tim Berners-Lee, a British computer scientist, made possible the sharing of information on a global scale, was a pivotal moment in the development of the internet.

Explanation

Choice C is the best way to combine the two sentences because it creates a grammatically correct sentence. The nonessential clause "which was created by Tim Berners-Lee, a British computer scientist" is set off with commas, and the two main clauses are joined with a comma and a coordinating conjunction. The other choices all result in grammatical errors: Choices A and D are comma splices; Choice B is a run-on sentence.
