I apologize, but without the questions I cannot confirm if those are the correct answers. Can you please provide the questions? Thank you.

The correct answer is d. his invention of the assembly line was used by other companies for mass production.

To arrive at this answer, you can consider the following explanation:
Henry Ford's most significant impact on other industries of the time was through his invention of the assembly line. The assembly line revolutionized manufacturing and allowed for mass production. Ford's introduction of this new production method led to significant changes in various industries.

By implementing the assembly line in his own car manufacturing business, Ford greatly increased efficiency and reduced production costs. This led to the production of cars at a significantly faster rate, making them more affordable for the general public. The success of Ford's assembly line approach quickly attracted attention from other industries.

Other companies, both within the automotive industry and beyond, recognized the potential of the assembly line to streamline their own production processes. They started adopting and adapting Ford's assembly line techniques to their own manufacturing operations. This resulted in a widespread shift towards mass production methods across various industries, including consumer goods, electronics, and more.

So, it was Ford's invention of the assembly line that influenced other industries at the time, as they began to adopt this method for their own mass production.
