Question Analysis
This question involves the factors influencing the speed of solute dissolving in a solvent. The main focus is on distinguishing between relevant and irrelevant factors for solution formation rate.

Key Concept Explanation
The rate of solution formation is determined by how quickly solvent molecules can interact with and surround solute particles. Key factors include:
Temperature: Higher temperatures increase solvent molecule kinetic energy, speeding up interactions.
Solute particle size: Smaller particles have larger surface areas, allowing more solvent contact.
Stirring: It brings fresh solvent into contact with undissolved solute and disperses dissolved solute away.

Step-by-Step Solution
1. List the known factors affecting dissolution rate: temperature, particle size, stirring, surface area.
2. Evaluate each option:
A (temperature): Affects kinetic ener...
