Answer: 3. [structure shown in figure]

Key idea: nylon 6,6 is made from hexamethylenediamine and adipic acid, linked by amide bonds.

Repeat unit: \(-[CO-(CH_2)_4-CO-NH-(CH_2)_6-NH]_n-\). Option 3 shows C=O, four \(CH_2\), C=O, then NH and \((CH_2)_6\)-NH. The other structures are not polyamides of this type.
