The correct answer is laws of gravity. Leonardo da Vinci did not formulate the laws of gravity; that was later accomplished by Sir Isaac Newton in the 17th century. The other two options, "Proportions of man" (referring to his famous drawing, the Vitruvian Man) and the "giant crossbow" (a design he created for a massive crossbow), were indeed accomplishments of Leonardo da Vinci.
