Answer is "basic".

NaOH is basic solution and it is a colorless solution. Due to the concentraion is 0.1 M, the solution contains 0.1 M of OH⁻ ions because NaOH fully dissociates into its ions as OH⁻ and Na⁺ in water.

NaOH → OH⁻ + Na⁺

pOH = -log[OH⁻]
        = -log(0.1)
        = 1
pH = 14 - pOH
     = 14 - 1
     = 13

Hence, pH of this G solution is 13 which is highly basic.
