Hint: Sperm is discovered by the Father of Microbiology. He was a renowned Dutch microbiologist. He was also the first acknowledged microscopist. In addition, he discovered Bacteria and Red Blood Cells.

Complete answer: Human sperm was discovered by the Dutch scientist Antione Philips van Leeuwenhoek. He is known as the Father of Microbiology. He discovered it in 1677. Antione Philips van Leeuwenhoek had developed a single-lens microscope of himself. He had created his own design. He referred to the sperms or the spermatozoa as animalcules, which is Latin for small animals. This is because he probably believed in preformationism. He believed that fully-formed small humans were contained inside the sperms.
-Aristotle was a Greek philosopher. He is known as the Father of Biology. He is also known as the Father of Zoology due to his noted works in this field.
-Graaf or Reinier de Graaf was a Dutch physician and anatomist. He is noted for his works in reproductive biology. He discovered the ovarian follicles. These were then named after him as the Graafian follicles.
-Pander was the Baltic German biologist and the embryologist. He discovered the three germinal layers. This is the reason he is known as the Father of Embryology.
Hence, the correct answer is option (A).

Note: Antione Philips van Leeuwenhoek is known as the father of microbiology because he discovered several microscopic organisms. Some important discoveries made by him include Infusoria protists, bacteria, cell vacuole, spermatozoa, the banded pattern of muscle fibers, red blood cells, and blood flow in capillaries.
