(D) The potential difference $V$ across the terminals of a cell discharging current $i$ is given by the formula: $V = E - ir$.Here,$E = 1.5 \, V$ is the electromotive force,$i = 2.0 \, A$ is the current,and $r = 0.15 \, \Omega$ is the internal resistance.Substituting the values into the equation:$V = 1.5 - (2.0 \times 0.15)$$V = 1.5 - 0.30$$V = 1.2 \, V$.Therefore,the potential difference across the ends of the cell is $1.2 \, V$.
