Let’s explore what the relationship between force and acceleration means in classical mechanics. 
Option 1: inversely. If force increased but acceleration were inversely related, we’d expect acceleration to decrease as force rises. This contradicts F = m a when mass is fixed, so this is incorrect. 
Option 2: directly. With a fixed mass, Newton’s second law states that acceleration is proportional to force (a = F / m). As force increases, acceleration increases proportionally, which aligns with the fundamental equation. This is consistent and correct. 
Option 3: almost. Saying acceleration is almost proportional suggests a near-but-not-quite linear relationship. In standard formulation with constant mass, the relationship is exact, so this hedges against the precise proportionality and is not accurate here. 
Option 4: not proportional. Claiming there is no proportionality contradicts the a = F / m relationship for constant mass, making this option false. 
In summary, the only option that mirrors the exact, linear dependence between force and acceleration (for a given mass) is the one stating a direct proportionality, while the others violate or soften this core relation.
