Answer:

7 octaves

Step-by-step explanation:

Total number of keys in piano = 88 keys

Numbers of keys in each group called octave= 12 unique keys

We have to find the number of complete octaves on piano

Number of octaves consists of 12 keys= $\frac{Total number of keys}{12}$

Number of octaves consists of 12 keys= $\frac{88}{12}$

Number of octaves consists of 12 keys= 7 octaves

Hence, the correct answer is 7 octaves
