Best Answer Explained in Below-:

The phrase "We've run ----- sugar" is a common way to express a lack of something essential, in this case, sugar. The best option among the selected choices is "B) out of," which accurately captures the intended meaning of having no sugar left.

When we say "We've run out of sugar," it indicates that there is no sugar remaining and implies a need to replenish it. This expression is widely used in everyday conversation when discussing things we consume or require regularly, making it a familiar and contextually appropriate choice.

The other options do not fit the context effectively:

A) "down on" is not a standard expression used in this context, and might suggest a decrease rather than a complete lack.
C) "on wait" is grammatically incorrect in this scenario and does not convey the idea of depletion.
D) "away from" similarly does not fit as it does not communicate the notion of running low or having no supply.

Thus, "out of" is the only logically and grammatically correct choice, as it clearly states the absence of sugar and the necessity to purchase more.
