Question

Which will change the order of a grid columns?

(a) .col-md-push-*

(b) .col-md-offset-*

(c) .clearfix

(d) .col-sm-*

Answer 1

Correct choice is (a) .col-md-push-*

The best I can explain: We can change order of the grid columns with .col-md-push-* and .col-md-pull-* classes, we can move columns to right using .col-md-offset class. .clearfix class clears float. A column layout for small device is done by .col-sm-*.
