Answer 1

The correct option is A The automotive industry began in the 1890s with hundreds of manufacturers who produced horseless carriages.

Since both sentences refer to the same subject, they can be joined with a relative pronoun. Hence, Option A is correct. The rest of the options do not combine the sentence at the underlined point but emphasises on other subjects, hence these are incorrect.
