To make the sentence grammatically correct and logically structured, the correct rearrangement is:
Although he was ill, he went to work. This structure is correct because it follows the appropriate syntax of placing the conjunction "although" at the beginning of the sentence, with a comma after it, followed by the main clause.
Step 1: Review of other options.
- (B) He to work went, although he was ill: This option is grammatically incorrect due to word order.
- (C) He was although ill, he went to work: This option is awkward and doesn't follow standard English sentence structure.
- (D) He although was ill went to work: This option is also incorrect due to incorrect word order.
Step 2: Conclusion.
The correct rearrangement is Although he was ill, he went to work.
Final Answer: Although he was ill, he went to work.
