In the Molecule, H-CºN, the VB Model Would Describe the Sigma

In the molecule, H-CºN, the VB model would describe the sigma bond between the C and the N as a combination of

A) 2p orbital on the C and a 2p orbital on the N.
B) 2p orbital on the C and a 2s orbital on the N.
C) 2s orbital on the C and a 2p orbital on the N.
D) a sp hybridized orbital on the C and a 2p orbital on the N.
E) a sp³ hybridized orbital on the C and a 2p orbital on the N.
