Answer: D. (i) and (ii) — only these two statements are directly supported by the passage.

1. Evaluate statement (i): The passage says 'Computers are ubiquitous... used in almost all fields from agriculture to space exploration.' This directly says computers are present in almost all places. Statement (i) is TRUE.
2. Evaluate statement (ii): Positive effect: computers improve efficiency. Negative effect: long hours cause health issues. Both are stated explicitly in the passage. Statement (ii) is TRUE.
3. Evaluate statement (iii): The passage says 'AI enables computers to learn' — it connects AI with computers, not independent of them. The claim that 'AI can be done without computers' is neither stated nor supported; in fact the passage implies AI needs computers. Statement (iii) is NOT supported.
4. Select the correct option: Only (i) and (ii) are deducible. The matching option is D.
