The ash which is collected after burning of magnesium ribbon is dissolved in water to give a solution X. What is the nature of the solution X when it is tested with indicators?

• A.  It turns blue litmus red and phenolphthalein pink, hence it is an acidic solution.
• B.  It turns red litmus blue and phenolphthalein pink, hence it is a basic solution.
• C.  It turns blue litmus red and gives no colour with phenolphthalein, hence it is an acidic solution.
• D.  It does not change colour of red or blue litmus and phenolphthalein, hence it is a neutral solution.
