Which choice best describes the distinction made in the text?

A. It clarifies that the limitation is ontological (nature of being) rather than technological.✓ Correct
B. It explains why our tools are broken.
C. It argues that particles don't exist.
D. It describes the cost of scientific equipment.

Key Evidence:

• "not a measurement error"

• "intrinsic property"

Why others are wrong: B (Explicitly says not error.), C (Matter exists.), D (No cost.).
