In a \( 0.5 \) molal solution \( \mathrm{KCl}, \mathrm{KCl} \) is \( 50 \% \) dissociated. The freezing point of solution will be \( \left(K_{f}=1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right) \) :
(a) \( 274.674 \mathrm{~K} \)
(b) \( 271.60 \mathrm{~K} \)
(c) \( 273 \mathrm{~K} \)
(d) none of these
