Explanation:

The Indian Council of Medical Research (ICMR) partnered with **India Post** for the delivery of COVID-19 testing kits to various destinations across the country. India Post, with its extensive network, was crucial in ensuring the timely and efficient distribution of these essential medical supplies, particularly to remote and underserved areas. Option (A) Amazon, Option (C) Snapdeal, and Option (D) Myntra are e-commerce companies primarily focused on retail and logistics for consumer goods, and while they have robust delivery networks, they were not the specific partner chosen by ICMR for this particular initiative. Thus, India Post was the key logistical partner for ICMR's COVID-19 testing kit distribution.
