Official Correct Choice:
Option B: High specific heat capacity
Concept:

Temperature stabilization implies resisting sudden fluctuations in internal or environmental temperature.

Solution:

  • Due to extensive intermolecular hydrogen bonding, water has a high specific heat capacity.


  • This means water has a great ability to absorb massive amounts of thermal energy with only a minimal change to its own temperature.


  • This property buffers cellular environments against extreme thermal shocks, acting as a crucial thermo-stabilizer.


Why other options are incorrect:

  • High heat of vaporization: Enables cooling through phase change (sweating), but specific heat capacity is what actively prevents the temperature from spiking in the first place.


  • High polarity: Relates to solvent properties, not thermal properties.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
