Answer 3

its pH value because word physical means touch.
flammability,reaction with oxygen and smell are chemical properties,they require chemical reaction but in case of smell,it is a consequence of chemical reaction.

and for pH ,we use scale and measured by touching that substance.
so i preferred pH value as answer.
