Best Answer Explained in Below-:

In C programming, the hierarchy of arithmetic operations is determined by operator precedence, which defines the order in which operations are performed. The correct order from highest to lowest precedence is:

1. Multiplication (`*`) and Division (`/`)
2. Addition (`+`) and Subtraction (`-`)

This means that multiplication and division are performed before addition and subtraction unless parentheses indicate a different order.

Among the given options, D (`/*+-`) correctly represents this hierarchy. The `*` and `/` operators have the same precedence and are executed first, from left to right, followed by the `+` and `-` operators which are executed subsequently.

In contrast, options A (`/+*-`), B (`*-/+`), and C (`+-/*`) incorrectly arrange the priorities such that the operations would not respect the standard precedence rules of C. For example, option A suggests that addition would happen before division, which is incorrect. Thus, option D is the accurate choice that reflects the true operator precedence in C, ensuring proper evaluation of expressions in programming.
