A particle \( \mathrm{X} \) moving with a certain velocity has a de
\( \mathrm{P} \) Broglie wavelength of \( 1 \AA \). If particle \( Y \) has a mass

W of \( 25 \% \) that of \( \mathrm{X} \) and velocity \( 75 \% \) that of \( \mathrm{X} \), de Broglie wavelength of \( Y \) will be:
(A) \( 3 \AA \)
(B) \( 5.33 \AA \)
(C) \( 6.88 \AA \)
(D) \( 48 \AA \)
