Answer:
C
Step-by-step explanation:
the unit right below yards is ft so we can mark out A
we also know that there are 3 feet in 1 yard and that in order for the unit yard to cancel out, the 1 yard needs to be the denominator to 3 feet, so we can mark out D
the unit right below feet is inches and we know that there are 12 inches in one foot, so we can mark out B
this leaves us with C
