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

1. A

   International Yoga Day, 2021

   International Yoga Day, 2021 was observed on 21 June with its own UN-linked theme centred on yoga and well-being, not “The Clock is Ticking”. That slogan does not belong to Yoga Day. This option is not the key.

2. B

   International Women's Day, 2021

   International Women's Day, 2021 was observed on 8 March with the campaign theme “Choose to Challenge”. It did not use “The Clock is Ticking”. This option is therefore wrong.

3. C

   World Tuberculosis Day, 2021

   World Tuberculosis Day, 2021 used the theme “The Clock is Ticking”. The day is observed every year on 24 March to mark the announcement of the discovery of the TB bacillus and to press for faster action against tuberculosis. The 2021 slogan underlined that time was running out to meet global TB targets, especially after pandemic disruption of services. That match makes (c) the official key.

4. D

   World Malaria Day, 2021

   World Malaria Day, 2021 falls on 25 April and used a malaria-specific slogan about reaching the zero-malaria target, not “The Clock is Ticking”. This option is not the key.

Summary. Official key is (c) World Tuberculosis Day, 2021. The WHO-linked theme for that year was “The Clock is Ticking”, stressing urgency on TB control. Yoga Day, Women's Day and Malaria Day in 2021 carried different official themes. World TB Day is fixed on 24 March. Only (c) pairs the given slogan with the correct day.
