【正确答案】：C
【题目解析】：在文中提到，购买桌布时需要考虑的一个重要因素是餐桌的形状和尺寸。对于圆形或圆角餐桌，最好选择圆形或椭圆形的桌布来覆盖。接下来，文中强调了确保桌布尺寸适当的重要性，以避免桌布太短而无法完全覆盖桌面，或者太长以至于给客人造成行走不便的困扰。 现在，我们有一个圆形餐桌，其直径为45英寸。为了选择合适的桌布尺寸，我们通常需要选择直径略大于餐桌直径的桌布，以确保桌布可以舒适地垂在桌子周围，但又不会太长。 现在来分析各个选项： A. 45-inch round（45英寸圆形）：这与餐桌的直径相同，因此桌布将不会垂在桌子上，不适合。 B. 50-inch round（50英寸圆形）：虽然比餐桌直径略大，但可能不足以提供足够的覆盖和下垂效果。 C. 70-inch round（70英寸圆形）：这是一个比餐桌直径大得多的尺寸，将允许桌布舒适地垂在桌子上，同时也不会太长。 D. 120-inch round（120英寸圆形）：这个尺寸过大，可能导致桌布过长，给客人造成不便。 综上所述，最合适的桌布尺寸是70英寸圆形，因此答案是C。
