The given solution of Urea is 0.1 M.

Hence, solution which is hypotonic to this solution of urea must have concentration less than 0.1 M.

Now,

0.9% w/v solution of glucose contains 0.9 g in 100ml solution

\therefore 1000ml solution contains 9 g of Glucose

\mathrm{\therefore \ Molarity = \frac{9}{180 \times 1}= 0.05\ M}  

Hence, the correct answer is Option (3)
