Electrocyclic reactions are a class of organic reactions where a ring system undergoes opening or closing, typically accompanied by the rearrangement of π-electrons. These reactions are quite intriguing as they involve the breaking or formation of σ-bonds in a cyclic compound.There are two main types of electrocyclic reactions:Ring Opening (Electrocyclic Ring Opening): In this type, a cyclic compound breaks open to form an acyclic compound. This can occur through either a conrotatory or disrotatory mechanism, which refers to the synchronous or anticlockwise rotation of substituents around the ring, respectively.Ring Closure (Electrocyclic Ring Closure): Here, an acyclic compound forms a cyclic compound by closing a ring. Similar to ring opening, this can also occur through conrotatory or disrotatory mechanisms.These reactions are governed by the Woodward-Hoffmann rules, which predict the allowed or disallowed nature of the reaction based on the symmetry of the molecular orbitals involved.

A catalyst forms an activated complex with the substrate ( commonly known as transition state which is highly unstable in nature) so the net activation energy of the reaction will decrease. That means reaction will proceed at lower energy. So rate of the reaction will be faster.
Hence option C is the correct answer.
