Choices

6

Choice-A

Choice A is incorrect. Without punctuation before "and", it sounds like "climate change and Ms. Johnson" is one item. This causes confusion in the list.

Wrong No change

7

Choice-B

Choice B is correct. The semicolon separates two detailed list items clearly: Dr. Smith (with a title) and Ms. Johnson (with her own description). Correct for complex lists.

Choice-D

Choice D is incorrect. A dash here is too abrupt and informal. It doesn’t correctly separate items in a list with internal punctuation like names and titles.

Wrong climate change- and
