Analysis of vegetative propagation structures:

• Correct: Ginger (Zingiber officinale) is propagated vegetatively through small sections of underground modified stems known as rhizomes (often referred to as 'seed rhizomes' or bits).
• Incorrect: Corms are propagation units for crops like gladiolus and Colocasia (taro).
• Incorrect: Stem tubers are used for the propagation of potato (Solanum tuberosum).
• Incorrect: While rhizomes are modified stems, the botanical propagation unit is specifically defined as a rhizome.

Meteorological classifications of rainfall events:

• Rainy day: According to the India Meteorological Department (IMD), a rainy day is officially defined as a period of $24$ hours (from $08:30$ IST to $08:30$ IST next day) with rainfall of $\gt 2.5\text{ mm}$ (or $\ge 2.5\text{ mm}$).
• Rainfall $\gt 2.0\text{ mm}$ is not an IMD official benchmark threshold.
• Rainfall $\gt 3.5\text{ mm}$ is incorrect.
• Rainfall $\gt 2.25\text{ mm}$ is incorrect.
