(C) During charging,the current $I$ in the circuit is given by the formula: $I = \frac{V_{supply} - E}{R + r}$.Here,$V_{supply} = 160 \ V$,$E = 10 \ V$,$R = 24 \ \Omega$,and $r = 1 \ \Omega$.Substituting the values: $I = \frac{160 - 10}{24 + 1} = \frac{150}{25} = 6 \ A$.The terminal voltage $V$ of the battery during charging is given by $V = E + Ir$.Substituting the values: $V = 10 + (6 \times 1) = 10 + 6 = 16 \ V$.
