Explanation

Antonie van Leeuwenhoek (B) was a 17th-century Dutch scientist who built his own powerful microscopes and became the first person to observe and document bacteria and other microorganisms, earning him the title "Father of Microbiology."

The distractors are wrong for these reasons:

  • Koch (A) was a 19th-century bacteriologist famous for developing Koch's Postulates and identifying specific disease-causing bacteria - he studied bacteria but did not discover them
  • Fleming (C) discovered penicillin (the antibiotic), not bacteria - a common mix-up due to the similar scientific context
  • Aselli (D) was an Italian anatomist known for discovering the lymphatic system, unrelated to microbiology

Memory tip: Think "Leeuwenhook" - he used a microscope like a hook to look at the tiny world for the very first time. The "lens" in his name can also remind you of his work with microscope lenses.
