Rearrange the parts of the sentence in correct order.
In Tamil nadu,
P-cows and bulls are worshipped and celebrated
Q-on Maattu Pongal,
R-and the finale is Jallikattu

Let's analyze the context and modifiers:
The sentence introduces a location: "In Tamil nadu,"

Part P ("cows and bulls are worshipped and celebrated") links perfectly as the subject-verb continuation after the location.

Part Q ("on Maattu Pongal,") provides the time or occasion for this celebration, logically modifying part P.

Part R ("and the finale is Jallikattu") adds a concluding fact with the coordinating conjunction "and".

Checking the order PRQ: "In Tamil nadu, cows and bulls are worshipped and celebrated on Maattu Pongal, and the finale is Jallikattu." This forms a grammatically correct and coherent sentence.
