The correct answer is: A. lower debt collection period.
A higher accounts receivable turnover ratio means that a company is collecting its receivables more quickly. This is a good thing, as it means that the company is not having to wait as long to get paid for its goods or services. A lower debt collection period means that a company is able to turn its receivables into cash more quickly, which can improve its cash flow and profitability.
Option B is incorrect because a higher accounts receivable turnover ratio means that a company is collecting its receivables more quickly, not more slowly.
Option C is incorrect because a higher accounts receivable turnover ratio does not necessarily mean that a company has lower sales. It is possible for a company to have high sales and a high accounts receivable turnover ratio, if it is able to collect its receivables quickly.
Option D is incorrect because a higher accounts receivable turnover ratio does not necessarily mean that a company has higher sales. It is possible for a company to have low sales and a high accounts receivable turnover ratio, if it is not able to collect its receivables quickly.
