Arrange the following solutions in order of their increasing boiling points.(i) \( 10^{-4} \, \text{M} \) NaCl(ii) \( 10^{-4} \, \text{M} \) Urea(iii) \( 10^{-3} \, \text{M} \) NaCl(iv) \( 10^{-2} \, \text{M} \) NaCl
\( \text{(i)} < \text{(ii)} < \text{(iii)} < \text{(iv)} \)
\( \text{(iv)} < \text{(iii)} < \text{(i)} < \text{(ii)} \)
\( \text{(ii)} < \text{(i)} = \text{(iii)} < \text{(iv)} \)
\( \text{(ii)} < \text{(i)} < \text{(iii)} < \text{(iv)} \)
