The argument concludes that a high amount of effort put into something (aligning a new wheel) is pointless, because the desired effect (perfect alignment) will not be permanent (wheels always shift).

Mismatched premises and conclusion. (B) concludes that an action (looking for parts), regardless of effort level, is rarely worthwhile, whereas the stimulus concludes that a high level of effort put into an action is always pointless. The stimulus supports its conclusion by claiming that the specific desired effect (matching paint) will not last, but (B)’s version of this is more akin to “don’t bother with matching paint because your house will crumble in 20 years.”

Mismatched premises and conclusion. The stimulus concludes that a high amount of effort put into something (matching paint) is pointless, because the desired effect (colors match) will not be permanent (color will fade). (C) concludes that a certain method (alternate shampoos) should be adopted for an effect (healthy hair), because of the consequences of not adopting the method (unhealthy hair).

Mismatched premises and conclusion. The stimulus concludes that a high amount of effort put into something (matching paint) is pointless, because the desired effect (colors match) will not be permanent (color will fade). (D) concludes that a thing is pointless (spending extra money) because the effect won’t be dramatic enough to be worth it.

Mismatched premises and conclusion. The stimulus concludes that a high amount of effort put into something (matching paint) is pointless, because the desired effect (colors match) will not be permanent (color will fade). (E) concludes that a thing is not worthwhile (matching dress and lining perfectly) because no one will notice the effect of its absence.
