Fricatives Are Formed By

Fricatives are formed by:

A) Constricting the airstream so that air rushes through with a hissing sound (e.g., "f", "v", "s")
B) A combination of a brief stopping of the airstream followed by a constriction (e.g., "w", "x")
C) Allowing air to flow around the tongue as it touches the alveolar ridge (e.g., "l", "r")
D) Allowing air to flow out through the nose to produce nasal sounds (e.g., "m", "n")
E) Interrupting airflow completely for a short time (e.g., "p", "b", "t", "d")
