Correct option is B
Correct Answer: B — Nitrocellulose
Explanation:
Nitrocellulose
- Correct spelling of the early film base compound
- Used historically in film production (highly flammable material)
Why others are incorrect:
- Nitrocelulose — missing one “l”
- Nitracellulose — incorrect prefix (“Nitra” instead of “Nitro”)
- Nitrocellullose — extra “l”
Hence, Option B is correct.
