Show answer and explanation

Answer: C. Items prone to shedding particles, such as ordinary paper and pencils

Ordinary paper sheds fibers easily, and pencils produce shavings and lead dust, so they cannot be used in cleanrooms. Lint-free paper and dedicated writing tools are used instead. Cosmetics and similar items may also be restricted because they generate particles.
