In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ?

Question

$\begin{array}{1 1} \text{intensity of central diffraction band will become 4 times } \\\text{intensity of central diffraction band will become 2 times } \\ \text{intensity of central diffraction band will be reduced 1/4 times} \\ \text{intensity of central diffraction band will be reduced by 1/2 times }\end{array} $
