"The Clock is Ticking" is the theme of which of the following days?

The answer is C, World Tuberculosis Day, 2021. The 2021 theme of World TB Day, observed on 24 March to mark Robert Koch's 1882 discovery of the TB bacillus, was 'The Clock is Ticking'. It highlighted the gap between the global TB targets and actual progress, and the urgency of meeting the 2025 UN High-Level Meeting commitments.

Why the others are wrong:

• A (International Yoga Day 2021): The theme was 'Yoga for Wellness'.
• B (International Women's Day 2021): The theme was 'Choose To Challenge'.
• D (World Malaria Day 2021): The theme was 'Zero Malaria Starts with Me'.

The core concept is that international days carry annual themes set by the sponsoring agency, and these are frequently asked. For Mains, link TB to India's commitment to end TB by 2025, through the National TB Elimination Programme, Ni-kshay portal and TB Mukt Bharat campaign, which is a good GS-II and GS-III health answer.

Trap: Aspirants often mix up the 2020 and 2021 TB Day themes or assign a malaria or Yoga Day slogan to the wrong date. Remember that the question asks for the 2021 theme specifically.
