Concept:Sentence rearrangement involves identifying the logical flow of ideas to form a grammatically correct and coherent sentence.
Explanation:Part C introduces the main event: the Sudanese Army said it was attacked by the RSF.
Part B follows naturally as it adds the location: "at its general command headquarters".
Part D continues by stating the army's action: "but had repelled the attack, inflicting 'heavy losses' on the RSF".
Part A then concludes with the result: "which had reportedly abandoned 24 vehicles".
Thus, the correct sequence is C → B → D → A.
This sequence forms a coherent sentence: "The Sudanese Army said it was attacked by the RSF at its general command headquarters, but had repelled the attack, inflicting 'heavy losses' on the RSF, which had reportedly abandoned 24 vehicles."
Answer:Option B (CBDA).
