What is the time signature that represents 4 beats in a measure, with the quarter note getting the beat?

The time signature that accurately describes 4 beats in a measure, with the quarter note getting the beat, is 4/4. In this time signature, the upper number indicates that there are 4 beats in each measure, while the lower number specifies that the quarter note serves as the unit of beat. This is a common time signature used in many styles of music, making it fundamental for understanding rhythm and meter.

The other options represent different rhythmic structures: 3/4 has 3 beats per measure, 2/4 has 2 beats per measure, and 6/8 is usually felt as a compound meter with 6 eighth notes grouped into two beats. Hence, none of these options fulfill the requirement of having 4 beats with the quarter note as the beat.
