read the following passage:
when you strum the d chord, begin with the fourth string. when you are using a brush strum, you may rest your thumb on the fifth string to avoid accidentally playing the fifth and sixth strings.
based on what you read, which of the following could you assume is true?
a. you should never rest your thumb on a string.
b. you should use a guitar pick to play a brush strum.
c. the d chord uses only four strings.
d. the d chord uses all six strings.

C: The D Chord uses only four strings.

Explanation:

It can't be A because the passage says you may rest your thumb on the 5th string. B is a possible answer but it gives an implicit choice, not explicit. D says the D Chord uses all six strings when the passage states to avoid playing the fifth and sixth strings.

Therefore, this evidence supports our answer that C is correct.
