Solution

The correct option is D
only d

The explanation for the correct answer:
Option (D): only d
Turmeric is a natural indicator that does not change its color in acidic solution but changes to red in basic solution.
Methyl orange is a type of artificial indicator which changes its color to red in acidic solution but changes to yellow in a basic medium.
So, in the case of turmeric acid does not cause color change but the base does.
and in the case of methyl orange both acid and base can cause a color change
So, option (D) is correct. The change of color in acid and base depends upon the type of indicators.
