B. Both are striated, but only cardiac muscle is involuntary.
✓
C. Both are non-striated and involuntary.
D. Both are attached directly to internal organs.

📝 Explanation

Correct: Both possess striations, but skeletal muscle is voluntary while cardiac muscle is involuntary. A: Cardiac muscle is usually uninucleate. C: Skeletal muscle is striated. D: Skeletal muscle is attached mainly to bones. Concept: Comparison of skeletal and cardiac muscles.
