Capillaries were discovered approximately how many years after Harvey's time?

Explanation:
Harvey’s work on blood circulation appeared in 1628, and the actual observation of capillaries came later when Marcello Malpighi used improved microscopes to study blood vessels, publishing findings around 1661. That makes the gap about 33 years—roughly three decades after Harvey. Since the options are approximate, the closest fit is about forty years, not sixty. The key idea is that capillaries were discovered a few decades after Harvey, once better microscopic tools allowed direct observation of the tiny connections between arteries and veins.
