Neither. They lack appropriate capitalization and punctuation.

match each word or phrase on the left

The grammatically correct sentence is: "Due to rain, the match was postponed."

To determine which sentence is grammatically correct, we need to look at the rules of capitalization and punctuation. In the first sentence, there is incorrect capitalization of "rain" in the middle of the sentence. In English, only proper nouns and the beginning of sentences need to be capitalized. Therefore, "rain" should be lowercase.

Additionally, the second sentence has repetition ("the match") and is missing a comma after "rain." In order to separate the introductory phrase "Due to rain" from the main clause "the match was postponed," a comma should be used.

Hence, the first sentence should be corrected to: "Due to rain, the match was postponed." This sentence is grammatically correct with appropriate capitalization and punctuation.
