Explain why cyclopropane (C ₃H₆) and cyclobutane (C₄H₈) are more reactive than other cycloalkanes. 

• A. Cyclopropane and cyclobutane are more reactive than other cycloalkanes because each bond angle they have deviates from the ideal 120°, resulting in ring strain and instability.
• B. Cyclopropane and cyclobutane are more reactive than other cycloalkanes because each bond angle they have deviates from the ideal 109.5°, resulting in ring strain and instability.
• C. Cyclopropane and cyclobutane are more reactive than other cycloalkanes because each of their bond angles is less than the ideal 90°, resulting in ring strain and instability.
• D. Cyclopropane and cyclobutane are more reactive than other cycloalkanes because each bond angle they possess is greater than the ideal 109.5°, resulting in ring strain and instability.
