3rd answer

Explanation:

The round circle in bold (w/out the stem) means a note that holds for 4 counts. A round empty note (w/ a stem) is a 2 count note. The 1st answer, the one with the x, means that the note is held for 1 count. Then, the 4th answer would be a rest. Counts go by seconds.

Sorry this is a bit confusing, but I hope I helped you understand :)

Option C, half note

Explanation:

Step 1:  Find the note

Since the one the have at first is a whole note, 4/4, they need a half note, 2/4.  To get a half note, you need to subtract a half note from a whole note.

4/4         -         2/4         =         2/4

whole               half                   half

4/4 - 2/4 = 2/4

2/4 = 2/4 -> Good
