Explanation:

A complex sentence has one independent clause and at least one dependent clause. The first option "My science class continued on its way to the abandoned gold mine even though an unexpected thunderstorm began" has the independent clause "My science class continued on its way to the abandoned gold mine" and the dependent clause "even though an unexpected thunderstorm began". The second option "An unexpected thunderstorm began, yet my science class continued on its way to the abandoned gold mine" is a compound - sentence with two independent clauses joined by "yet". The third option "My science class continued to the abandoned gold mine as a thunderstorm, which was unexpected, began" has the independent clause "My science class continued to the abandoned gold mine" and the dependent relative clause "which was unexpected" modifying "thunderstorm" and the adverbial clause "as a thunderstorm began". The fourth option "My science class continued on its way to the abandoned gold mine; meanwhile, an unexpected thunderstorm began" is a compound - sentence with two independent clauses separated by a semicolon and "meanwhile".

Answer:

My science class continued on its way to the abandoned gold mine even though an unexpected thunderstorm began.
