Correct Answer:
Option C —
Omicron
Key Details of the Omicron VariantDiscovery: It was first reported to the WHO from South Africa on November 24, 2021, though the first known confirmed specimens were collected in Botswana and South Africa in early November.
Mutations: Omicron is notable for its unusually high number of mutations—approximately 50 in total, with more than 30 mutations in the spike protein alone. These mutations are what led to concerns about increased transmissibility and immune evasion.
Naming Convention: The WHO uses the Greek alphabet to name variants to avoid stigmatizing the countries where they are first detected. Interestingly, the WHO skipped the letters Nu (to avoid confusion with the word "new") and Xi (to avoid confusion with a common surname) before settling on Omicron.
