does the word "Option" have an analogue in Japanese

Question

In English, we use the word "option" in a wide array of situations with many different meanings. When speaking, I struggled to find a word that translated the meaning effectively. Some examples are:

Giving up is not an option.

In this case I assume there is not a direct translation, and I have to use あきらめるわけにはいかない or something of the sort?

There are many drink options at that restaurant.

This is another usage that confuses me. I feel like たくさんの種類 maybe works, but that there is still a better way to say this.

What are our options?

or

That idea, won't work, we need to find another option.

This is the usage that really gets me. I am not aware of a word that exists such that I can say, 僕らはほかの＜option＞を探さない/見つけないといけない

Answer 1

The word 選択肢 can be used, possibly with small rephrasing, like this:

• 諦めるという選択肢はない。
• このレストランにはたくさんのドリンクの選択肢がある。
• 我々の選択肢は何か？
• その案はダメだ、別の選択肢を探さないと。

Still, 選択肢 is a relatively stiff word, and yes, something like 諦めるわけにはいかない may be a reasonable choice in casual speech. If you feel like avoiding 選択肢, you can say たくさんのドリンクから選べる, どんな案があるか, 別の方法を探そう, etc.
