Which among the following can be deduced from the following the graph between Energy and progress of reaction?

Positive catalyst increases the activation energy of the reaction.
Positive catalyst increases the rate of reaction.
Negative catalyst decreases the activation energy of the reaction.
All of the above.
Positive catalyst decreases the activation energy of the reaction resulting into increase in the rate of reaction. On the contrary, negative catalyst increase the activation energy and thus, decreases the rate of reaction.
