Correct answer: B. Point prevalence
Explanation
A cross-sectional survey assesses the presence of disease at a single point in time, measuring point prevalence.

Attack rate is a specific type of incidence used to measure disease frequency during an outbreak. Prevalence is a snapshot, whereas incidence captures new events.
