A linear aperture whose width is \( 0.02\text{ cm} \) is placed immediately in front of a lens of focal length \( 60\text{ cm} \). The aperture is illuminated normally by a parallel beam of wavelength \( 5 \times 10^{-5}\text{ cm} \). The distance of the first dark band of the diffraction pattern from the centre of the screen is

1. A
   \( 0.15\text{ cm} \)
2. B
   \( 0.10\text{ cm} \)
3. C
   \( 0.25\text{ cm} \)
4. D
   \( 0.20\text{ cm} \)
