Correct answer: B
Correct Option: B
Explanation: Laboratory production of antihelium nuclei helps test matter–antimatter symmetry and explore cosmological questions.
Statement/Item-wise Analysis:
1: Incorrect - Producing rare antimatter nuclei does not make routine mineral prospecting cheaper.
2: Correct - Antihelium research improves searches for antinuclei that might indicate antimatter cosmic sources.
3: Correct - Antimatter studies inform theories of the early universe and matter–antimatter asymmetry.
Option-wise Analysis:
A: Incorrect - includes incorrect item 1; omits correct items 2, 3.
B: Correct - includes exactly the valid statements/items and excludes the invalid ones.
C: Incorrect - omits correct item 2.
