Q. The words “wall of separation between church and state” appear in the Constitution.

a. true
b. false

This question refers to the First Amendment of the U.S. Constitution.

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."

b. false

Explanation:
The words "wall of separation between church and state" do not appear in the Constitution. This phrase is often attributed to Thomas Jefferson in a letter he wrote to the Danbury Baptist Association in 1802, where he used the phrase to explain his belief in the need for a clear separation between religious institutions and the government. However, this specific wording does not appear in the Constitution itself. The First Amendment of the United States Constitution, however, does include language that protects the freedom of religion and prohibits the government from establishing a state religion or interfering with the free exercise of religion.
