Capital budgeting decisions are long-term investment decisions and are influenced by key financial metrics and project fundamentals. The relevant factors include:
\begin{itemize}
\item Cash flow of project (B): Since capital budgeting evaluates future returns, cash flow is a primary determinant.
\item The rate of return (D): Determines the profitability of the investment.
\item The investment criteria involved (E): Includes techniques like NPV, IRR, Payback Period etc., which guide the investment decision.
\end{itemize}
Floatation cost and control considerations, although relevant in financing and strategic decisions respectively, do not directly affect capital budgeting.
