The president is able to check power of congress by

a. vetoing laws passed by congress.

b. filibustering bills to prevent a vote.

c. preventing bills from being sent to commitee

d. setting the rule of congress debate

Correct  A.  vetoing laws passed by Congress.

This is a significant power in the hands of the President.  Congressional decision making is affected by the knowledge that in both houses of Congress, a two-thirds majority will be needed to override the President's veto.  Historically, Congress has been able to override less than 10% of presidential vetoes.  So Congress will seek to make sure they have sufficient votes before proceeding with passage of a bill into law ...  unless they want to pass the legislation simply as a statement of principle, knowing they don't have the votes to override a veto.
