The number of radial nodes of 3s and 2p orbitals respectively are 2 and 0 respectively. Number of radial nodes \\\\(\\displaystyle = n - l -1\\\\)For 3s orbital, number of radial nodes \\\\(\\displaystyle = 3-0-2 = 2\\\\)For 2p orbital, number of radial nodes \\\\(\\displaystyle = 2-1-1 = 0\\\\)Hence the correct option is B.
