C) they use shorthand symbols to represent quantities.
D) they are predefined for each programming language.

Option B is correct.

Explanation:

Let look at each statement

A) No, Conditional statement do not eliminate extra code by reuse.

B) Yes, it allow programmers to set conditions to be met for an action to take place. so this option is correct.

C) No, shorthand symbols are not used to represent quantities.

D) No, They are not Predefined for each programming Language.

the answer is B, The Second Opinion

Explanation:

the Conditional Statement or in other words the if Statement is used in a code to set conditions so when the need of the function is met true, then the code can execute the function.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
