Answer :
The technique of plucking a violin string with the finger is called A) pizzicato.
Pizzicato involves the musician using their finger to pluck the strings of a bowed string instrument, such as the violin, viola, cello, or double bass, rather than using a bow. The resulting sound has a distinctive percussive effect, different from the sustained notes produced when bowing the strings.
In contrast, the other options are unrelated techniques: consort refers to a group of instruments or musicians playing together, legato denotes a smooth and connected style of playing, and tremolo indicates rapid repetition of a single note.
