Question

which detail is a limitation of a promotional offer that boosts a credit score?
it can lead to higher interest rates in the long term.
it often only gives a credit score a temporary boost.
it only affects buying power, not the credit score.
it permanently improves earning power.

Explanation:

A promotional offer that "often only gives a credit score a temporary boost" is a limitation. Promotions aiming to boost credit scores usually have short - term impacts. Once the promotional period ends, the factors that contributed to the score increase (like a new credit line with a promotional rate) may change. For example, if there was a 0% interest promotional credit card, after the promotion ends, the interest rate might go up. If the cardholder struggles with higher payments due to the new rate, it could negatively affect their credit score in the long run. So, the temporary nature means it's not a sustainable improvement, which is a clear limitation.

Answer:

It often only gives a credit score a temporary boost.
