All of 1, 2 and 3 can produce alkanol (ethanol)directly.

1. Ethylethanoate produces ethanol in saponification (alkaline hydrolysis).
CH3COOCH2CH3 + NaOH → CH3COONa + CH3CH2OH

2. Ethene produces ethanol in catalytic hydration.
CH2=CH2 + H2­O → CH3CH2OH(H3PO4 as catalyst)

3. Glucose produces ethanol in fermentation.
C6­H12O6 → 2CH3CH2OH+ 2CO2 (enzyme from yeast as catalyst)

definitely 1 and 3 only

1. by hydrolysis
3. by fermentation
to get ethanol.

ethene is C2H2 does not have the oxygen for the -OH group.
