Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Sour taste is primarily mediated by the activation of GPCR T1R3 (G-protein coupled receptor), which is involved in detecting acidic substances. The T1R family of receptors, including T1R3, play a key role in the detection of basic taste sensations like sweetness and sourness.
