b)the practice of judicial review
c)the unwritten constitution
d)article i of the constitution

The correct answer is C. The two major political parties in the United States are considered part of the unwritten constitution.

Explanation:

The "Unwritten Constitution" is the series of legal, judicial and ethical precepts that, although not included in the Constitution, are part of the fundamental pillars that organize the government and guarantee the preeminence of the rule of law in the nation.

These are concepts that govern the country because they are fully accepted by society, which identifies positive results in them. In this sense, the existence of two predominant political parties (Democrats and Republicans) that agglutinate and monopolize the vast majority of the national political spectrum is socially accepted and considered positive, since it is considered to generate political and partisan stability, which may not exist in case of a multiplicity of political parties.
