Theophrastus (371-287 BC) was a Greek philosopher and student of Aristotle who made significant contributions to the study of plants, earning him the title 'Father of Botany.' He wrote major works like 'Enquiry into Plants' and 'On the Causes of Plants,' establishing botany as a scientific discipline.

Democritus, the ancient Greek philosopher (c. 460-370 BC), coined the term 'atom' from the Greek word 'atomos' meaning 'uncuttable' or 'indivisible'. He proposed that all matter consists of tiny, indivisible particles called atoms. While his teacher Leucippus also contributed to atomic theory, the actual term 'atom' is attributed to Democritus.

He developed the atomic theory proposing that all matter consists of tiny, indivisible particles. While his teacher Leucippus also contributed to atomic theory, Democritus is specifically associated with naming atoms.

Archimedes discovered the principle of buoyancy (now called Archimedes' Principle) while trying to determine if a crown was pure gold without damaging it. He realized that a crown would displace water equal to its volume, and a gold crown would displace differently than one mixed with silver. This became known as the 'Eureka' moment in the bath.

Albert Einstein developed the Theory of Relativity, which revolutionized our understanding of space, time, and gravity. Special Relativity (1905) established that space and time are relative to the observer's motion, while General Relativity (1915) described gravity as the curvature of spacetime caused by mass and energy.

Bartolomeo Cristofori invented the piano (originally called the gravicembalo col piano e forte, meaning 'harpsichord with soft and loud') around 1700 in Florence, Italy. His breakthrough was the hammer mechanism that struck strings instead of plucking them, allowing players to control volume through touch - impossible on harpsichords. This enabled dynamic expression in keyboard music.

Galileo did all three: he significantly improved the telescope design (though didn't invent it), discovered four moons of Jupiter (the Medicean stars), and discovered the pendulum's isochronism which led to accurate timekeeping. While the first option is slightly imprecise, the question intends D as the correct answer.
