What is its rotational energy in the $L = 0$ quantum state? $\left( 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J} , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)$

A) $6.0 \times 10 ^ { - 5 } \mathrm { eV }$
B) $9.0 \times 10 ^ { - 5 } \mathrm { eV }$
C) $0 \mathrm { eV }$
D) $3.0 \times 10 ^ { - 5 } \mathrm { eV }$
