Experts I have question, what if the option E would have been "
three important ideas that are physical in nature". which option to chose then between A and E?
In his laws of motion, which now form the core of classical mechanics, Isaac Newton clearly and concisely introduced three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces.
(A) three important physical ideas: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces
(B) three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature
(C) three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces
(D) three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces
(E) three important ideas that were physical in nature: the concept of inertia, the relationship between force and acceleration, and the coupled nature of forces
