AIIMS 2019 Physics Surface Tension Assertion Reason Question

Water droplets take an oval shape when falling freely due to surface tension, which minimizes the surface area for a given volume, leading to a spherical shape in the absence of other forces. The assertion that water's surface tension is not the minimum among all liquids is true, as liquids like mercury (Hg) have higher surface tension. Therefore, the assertion is true, while the reason is also true but does not directly explain the assertion, making option D the correct choice. Other options are incorrect because they either misrepresent the truth of the assertion and reason or do not provide a valid explanation for their relationship.
