Consider the following setup: Each of five students - Hubert, Lori, Paul, Regina, and Sharon - will visit exactly one of the 3 cities - Montreal, Toronto, or Vancouver - for the month of March, according to the following conditions:

Sharon visits a different city than Paul.

Hubert visits the same city as Regina.

Lori visits Montreal or else Toronto.

If Paul visits Vancouver, Hubert visits Vancouver with him.

Each student visits one of the cities with at least one of the other four students.

Q: Which one of the following is a complete and accurate list of students any one of which could visit Vancouver in March?

a. Hubert, Lori, Regina

b. Hubert, Regina, Sharon

c. Paul, Regina, Sharon

d. Hubert, Paul, Regina, Sharon

e. Hubert, Lori, Paul, Regina, Sharon

In the book, the answer says it is D. At first I was confused because it says Paul can't visit with Sharon and D. says they both do. However, in the book it says that for "any one of which" questions, "it doesn't matter whether any of the other students on the list could also visit Vancouver at the same time," so I guess for these "any one of which" questions, one person visiting isn't conditional on another person visiting even though the rules might say so? Thanks in advance for explaining this analytical reasoning question, it's for LSAT prep.
