B Correct answer
Explanation

Malarial parasites (Plasmodium) rupture from red blood cells synchronously, causing the characteristic fever spikes. The parasites are most abundant in peripheral blood immediately after the temperature rise, which corresponds to the release of merozoites from infected RBCs. This timing offers the best chance for detection in blood smears.
