Which question is most important while checking the feasibility of an enterprise?

Correct answer: क्या यह समस्या हल करता है और टिकाऊ आय दे सकता है?

Feasibility asks whether an idea can work in practical conditions. The entrepreneur should examine whether the offering solves a genuine problem, whether customers value it enough to pay, and whether expected income can cover costs over time. A name, logo or large office may matter later, but none establishes economic or operational feasibility alone.
