कमी तापमानाच्या वस्तूतून उच्च तापमानावरील वस्तूत, उष्णता स्थानांतरण _______.

Option C is correct because the second law forbids spontaneous heat flow from cold to hot, but a refrigerator or heat pump can transfer heat uphill by doing external work on the working fluid. Option C encodes that thermodynamic exception; mere contact (B) or 'impossible' (A) ignores engineered refrigeration cycles. Distractors A (impossible), B (possible by keeping both the bodies in …), D (None of the above) look plausible but do not follow from the facts stated in the question. MPSC papers often recycle this type of detail, so read the question carefully before you commit to an option.
