If the radius of the first Bohr’s orbit of the H-atom is x, which of the following is the correct conclusion? 

The second Bohr’s radius of $B{e}^{3+}=x$

The fourth Bohr’s radius of $H{e}^{+}$ ion $=8x$

The de-Broglie wavelength in the third Bohr orbit of the H-atom $=6\pi x$

The de-Broglie wavelength in the third Bohr orbit of $L{i}^{2+}=2x$
