Step 1: Meaning of "locus standi''
- It is a Latin phrase meaning "place to stand.''
- In law, it refers to the right or capacity of a person or party to bring a lawsuit or appear in court.
- It ensures that only persons with a sufficient interest in a case can sue.
Step 2: Why other options are incorrect
- (A) Physical location is the venue, not locus standi.
- (C) Judge's authority is jurisdiction or power, different term.
- (D) Jury selection is called voir dire, unrelated here.
Therefore, option (B) is correct.
