"the concentration of acid in the solution has been increased"

Reason: Strength (a property like Ka — whether it's a strong or weak acid) doesn't change by adding more acid. Adding 5 ml to the original 10 ml increases the amount of acid (by 50%), so the concentration goes up (new concentration ≈ 1.5× the original, assuming volumes are additive).
