The correct answer is B. Keywords help narrow the focus.

Explanation

The keywords are a set of concepts that mark the main themes of a text, an investigation, a news item, among other documents. This set of words is generally used to focus research on more specific issues. For example, if someone wants to investigate the incidence of climate on fruit plants in tropical areas, they can use keywords "tropical areas" "fruit plants" "climates in tropical areas" among others to find more specific information to help them solve your investigation. So, the correct answer is B. Keywords help narrow the focus.
