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

This tests the correct use of the punctuation, the colon (:). A colon used at the end of a clause must be immediately followed by the elements the clause seeks to talk about in a structurally and logically parallel pattern. Let us now analyze choice by choice
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 ------ correct use of colon followed by parallel elements --- keep it for the time being
three important physical ideas; the concept of inertia, the relationship between force and acceleration, and that forces were coupled in nature -- 1.wrong’semi - colon is used. What follows a semi colon should be an independent clause. 2. The three elements are not //.
[c] three important physical ideas; the concept of inertia, force and acceleration were related, and the coupled nature of forces ------- wrong as in B
[d] three important physical ideas, the concept of inertia, the relationship between force and acceleration, and he also introduced the coupled nature of forces ------ wrong ---the three elements are not //
[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. Correct use of colon and correct //ism; -----keep it for the time being.
Now there is a problem with E. The three important [b]ideas that were physical in nature is a deviation from the text’s version ‘three important physical ideas’. Of course, it is a tough thing to discriminate between the two. When we say in past tense that three important ideas that were physical in nature, we mean that they were physical at the time of his introduction of those ideas, perhaps not earlier nor later. However, in reality, they are eternally physical and avoiding the past tense would be a clear expression. Of course, we might even say A is concise while E is wordy. All said and done, A is markedly better.
Of course, I am taking ‘physical’ as ‘physics – related’, for want of any other befitting reason
