View answer and explanation

Correct option: A

{\mathrm{I}^{\mathrm{st}}}\mathrm{\;IE\;of\;C} > {\mathrm{I}^{\mathrm{st}}}\mathrm{\;IE\;of\;B}

The correct answer is A (

{\mathrm{I}^{\mathrm{st}}}\mathrm{\;IE\;of\;C} > {\mathrm{I}^{\mathrm{st}}}\mathrm{\;IE\;of\;B}

) because carbon has a more stable electronic configuration than boron, leading to a higher ionization energy.
