Identify the trading strategy that will generate the payoffs of taking a long position in a put option within a single-period binomial framework.

A. Short sell $–h = –(p^+ – p^–)/(S^+ – S^–)$ units of the underlying and financing of $–PV(–hS^– + p^–)$
Buy $–h = (p^+ – p^–)/(S^+ – S^–)$ units of the underlying and financing of $– PV(–hS^– + p^–)$
C. Short sell $h = (p^+ – p^–)/(S^+ – S^–)$ units of the underlying and financing of $+PV(–hS^– + p^–) $
