Which of the following directive facilitates you to generate styles in a loop?

A) @if

B) @for

C) @each

D) @while

Correct Answer : @for

Explanation : The @for directive facilitates us to generate styles in a loop. The @for directive comes in two forms. The first option is @for $var from <start> through <end> which starts at <start> and loops "through" each iteration and ends at <end>. The second option is @for $var from <start> to <end> which starts at <start> and loops through each iteration "to" <end> and stops. Once the directive reaches the <end>, it stops the looping process and does not evaluate the loop that one last time.
