Answer 2

The correct option is c.

• Nucleophiles are nucleus loving species.
• Nucleophiles either contain a negative charge or lone pair of electrons.
• The species $CN^-$ has a negative charge so, it acts as a nucleophile.
• The species $RCH^{-2}$ has a negative charge so, it acts as a nucleophile.
• The species $ROH$ has a lone pair so, it acts as a nucleophile.
• The species $BF_3, AlCl_3$ is a lewis acid so, it does not act as a nucleophile.
