The correct option is c rainwater.
- When a strip of pH paper is dipped in the aqueous solution of a substance X, the colour of the pH paper changed from orange to yellow then the substance is most likely to be rainwater.
- Rainwater have acidic pH around 5-5.5
- This acidic pH turns pH paper color orange to yellow.
