• Option A is correct: The sensor was indeed developed by a research team at the Central University of Kerala led by Dr. Ravi Kumar Kanaparthi and is highly sensitive and selective for detecting cyanide, enhancing safety in water and food products. • Option B is incorrect: The sensor changes color from yellow to colorless upon detecting cyanide, not the other way around. • Option C is incorrect: While the WHO limits cyanide concentration in water to 0.19 mg/L, the sensor is designed to detect even lower concentrations, not just those above this limit. • Option D is incorrect: The sensor was tested on cyanide detection in tapioca extracts, not mango extracts. • Option E is incorrect: The findings were published in the Journal of Photochemistry and Photobiology A: Chemistry, not in the Journal of Analytical Chemistry.
