Consider an electron in the \( \mathrm{n}^{\text {th }} \) orbit of a hydrogen atom in the Bohr model. The circumference of the orbit can be expressed in terms of the de Broglie wavelength \( \lambda \) of the electron as :
(a) \( (0.529) \mathrm{n} \lambda \)
(b) \( \sqrt{\mathrm{n}} \lambda \)
(c) \( (13.6) \lambda \)
(d) \( \mathrm{n} \lambda \)
