would the sentence "Time is Money!" be a good opening line for a letter urging a group of international business executives to come to an immediate decision about an investment opportunity?

a. yes, because then they would realize that a delay could hurt them financially
b.yes, because it shows that you have a reason for pushing them on their decision
c. no, because it emphasizes that you are asking the group to spend money in the first place and their reluctance to so ould be the cause of the delay.
d. no, because people in other countries often take a much more leisurely approach to negotiations; they may want to establish a personal relationship before they decide whether to do business with you or not and that takes time

Is C correct?

Wow! It could be any of them. What else do you know about the situation?

that its a group of international business executives so they would have to gather information about this investment if it would be a good choice

I agree that C is the best answer.

What do you think of D?

Leisurely negotiations vary by country and culture. It doesn't apply to Europe and Canada.

Yes, option C is correct. The sentence "Time is Money!" may not be a good opening line for a letter urging a group of international business executives to come to an immediate decision about an investment opportunity. It emphasizes that you are asking the group to spend money, which could potentially cause reluctance and slow down the decision-making process. The emphasis on money may not be as effective as other approaches when dealing with international business negotiations, where relationship-building and personal rapport often play significant roles.
