Correct option is D

Correct Option-d)
In Indian classical music's tala system, an Anga refers to a basic time-unit component of a rhythmic cycle. Information Booster:
· The akshara kala (time duration) of the anga Druta is 2.
· Druta is one of the three fundamental time-measures (Angas) in the ancient Tala system, specifically in the Suladi Sapta Talas of Carnatic music and analogous Hindustani theory.
· It is symbolically represented by a circle (O) and is defined as having two aksaras (counts or beats). It is precisely twice the duration of the shortest unit, Anudruta (1 count).
· In practice, a Druta is often clapped once and then waved, representing a total of two beats.
Additional Knowledge:
· 1 is the akshara kala of Anudruta, the shortest unit.
· 4 is a common akshara kala for a Laghu of the Chaturasra Jati (type), not for Druta.
· 8 is not the standard count for any single, basic Anga; it would be the combined duration of multiple angas (e.g., two Drutas of 2 counts each plus a Laghu of 4 counts).
