Answer 2

Two electrons are contributed by O in furan to aromatic sextet. (option b)

• There is a contribution of two electrons by oxygen in furan in order to maintain the aromaticity of the furan compound.
• The furan compound gets stabilized when it is $sp^2$ hybridized.
• The compound obeys Huckle's rule in order to confirm that there is a contribution of two electrons and 6pi electrons are formed.
• In the formation of the $sp^2$ hybridized atom, a conjugated compound is formed, which makes the furan compound more stable.
