Instruction: Identify the assumptions that must hold for the statement to be valid, then choose the correct option.
Statement: The discovery of exoplanets in habitable zones around distant stars has provided exciting prospects for the search for extraterrestrial life, yet the vast distances and technological limitations pose significant obstacles to direct exploration.
Assumptions:
I. Exoplanets located in habitable zones may have the potential to support life.
II. Current technology is insufficient to directly explore exoplanets in habitable zones.
III. Direct exploration of exoplanets will be unnecessary if we detect signs of life remotely.
- A.
Only I and II are implicit
- B.
) Only II and III are implicit
- C.
Only I is implicit
- D.
All assumptions are implicit

Correct answer: A
The statement assumes that habitable-zone exoplanets may support life and that current technology cannot directly explore them. It does not require the claim that remote detection would make direct exploration unnecessary.
