A viable option is something that's possible or has a chance of happening. It's like a real choice or opportunity.
When we talk about something being viable, we usually mean it's working well or has a good chance of succeeding. For example, if someone asks "Is this business idea viable?" they want to know if it's a sound plan that could actually work. We might say a new restaurant is viable because it's got a lot of customers and seems to be making money. Or we might talk about a new technology being viable for use in our daily lives, meaning it has the potential to become widely accepted or useful. In these cases, "viable" implies something that's real, practical, and not just an idea that sounds good on paper but won't actually work out.
An organism that is able to live and develop.
Able to live on its own (as for a newborn).
