Answer:
Chemical properties,
Explanation:
Let us understand all the given terms
a) catalyst properties: this is the property of a substance by virtue of which it helps to modulate the rate of reaction, and itself remains unconsumed during the reaction (does not react). Example : enzymes
b) chemical properties: this is the property of a substance by virtue of which it reacts with another substance to give a new product of different structure, bonding, chemical and physical properties.
Example : hydrogen reacts with oxygen to give water.
So here the hydrogen is undergoing reaction with oxygen and this is chemical property of hydrogen.
c) Physical properties: This is the property which is related to the nature of a substance to exit in nature. for example hydrogen is a gas is its physical property not chemical.
d) mineral properties: It is again a kind of physical property.
