The answer is: D.oxymoron.
The oxymoron is a combination of contradictory or incongruous words.
In this example, deafening silence.
Deafening is a noise so loud as to make it impossible to hear anything else.
Silence is oposite of deafening, complete absence of sound.

Among the choices given, the best answer is the third option. Melting ice shows an increase in entropy. Entropy is the degree of disorderliness in a system. Among the phases, solid has the most ordered structure which means it has the least entropy. The ice melting shows a phase change from solid to liquid. Liquid molecules are more disorganized than the solid thus there is an increase in entropy.
Answer: melting ice
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
1. condensation of water : Condensation process is a process where gaseous state changes to liquid state., thus decreasing randomness and decreasing entropy.
2. Freezing water : Freezing process is a process where liquid state changes to solid state, thus decreasing randomness and decreasing entropy.
3. melting ice: Fusion process is a process where solid state changes to liquid state, thus increasing randomness and increasing entropy.
4. deposition of : deposition process where gaseous state changes to solid state by escaping liquid state, thus decreasing randomness and decreasing entropy.
