Answer 1

people were running away in all directions

Answer 2

People c) were running away in all directions.

When to use were?

• Whereas was is indeed the singular past tense of it to be, were is being used for both the third person plural past tense (they and we) as well as the second person past tense (you).
• Acts comparable to were performed in the past indicative.
• "They were in the shop," for example.

In this sentence, People is plural so using were is correct option.
