The following question gives a sentence which has been divided into four parts which may not be in their correct order of narrative. The sentence is then followed by five options, one of which gives the sequence of the rearranged parts to make the sentence meaningful. Choose the option which gives the correct sequence of the parts. If the sentence is already arranged in the correct sequence, mark option " No rearrangement required " as the answer.

To arrange the given sentence fragments into a coherent, grammatically correct, and meaningful sentence, let us analyze each segment carefully:

(A) March 2026 was the
(B) with an El Niño likely to push
(C) temperatures even higher
(D) hottest on record in the US,

Step 1: Identify the opening segment.
Segment (A) introduces the subject and verb: "March 2026 was the". This naturally requires a superlative adjective or noun phrase following "the" to complete the clause.

Step 2: Connect the subject to its complement.
Looking at the options, segment (D) "hottest on record in the US," perfectly completes segment (A): "March 2026 was the hottest on record in the US," forming a complete main clause.

Step 3: Connect the modifier/prepositional phrase.
Segment (B) "with an El Niño likely to push" introduces a prepositional phrase ("with...") providing extra context about the ongoing weather phenomenon. Placing (B) after (D) flows logically: "...hottest on record in the US, with an El Niño likely to push".

Step 4: Complete the infinitive phrase.
The verb phrase "likely to push" in segment (B) requires an object/destination. Segment (C) "temperatures even higher" completes this action: "push temperatures even higher".

Step 5: Review the combined sequence.
Putting the segments together in the sequence A → D → B → C gives:
"March 2026 was the hottest on record in the US, with an El Niño likely to push temperatures even higher."

This sentence is grammatically sound, fluent, and meaningful.

The correct option is ADBC.
