How many fricative sounds are there in English?

Correct option is C

There are a total of nine fricative consonants in English: /f, θ, s, ∫, v, ð, z, З, h/, and eight of them (all except for/h/) are produced by partially obstructing the airflow through the oral cavity.
Fricative consonants are made by squeezing air between a small gap as it leaves the body.
