Answer 1

The `"activation energy"` can be affected by `(d)`, i.e. none of the given options...............

Explanation:

As shown on the diagram, a CATALYST can have an effect on the activation energy of a particular reaction. A catalyst has NO EFFECT whatsoever on `DeltaH`, the enthalpy change of the reaction.

In the uncatalyzed reaction, the activation energy may be supplied by increasing the temperature, but it is essentially constant.
