★(c) F > N > C > B > Si

★Reason

• In a period as we move from left to right, non metallic character increases because of decrease in the size of the atom which leads to increase in tendency to accept electron from left to right. Even in a group, non metallic character decreases due to increase in size which leads to decrease in tendency to accept electron from top to bottom.
