Which of the following examples has three beats in each measure?
ת נהנתנ oa
ת נולת נ o b
וגנר נ 2 .o c
נ נתתננ .o d

B.

Explanation:

The example where we can see three beats in each measure is B.

In the first measure, we have a quarter note, two eighth notes, and another quarter note. That is three beats (1 + 1 + 1).

In the second measure, we have one half note and one quarter note. That is three beats as well (2 + 1).

So, each eighth note is half a beat long, each quarter note is one beat, while a half note is two beats long.
