What is the correct structural formula for 3-chloro-2-methylpent-3-enoic acid?
CH3CH2C(Cl)=C(CH3)COOH\text{CH}_3\text{CH}_2\text{C(Cl)}=\text{C}(\text{CH}_3)\text{COOH}CH3CH2C(Cl)=C(CH3)COOH
CH3CH(CH3)C(Cl)=CHCOOH\text{CH}_3\text{CH}(\text{CH}_3)\text{C(Cl)}=\text{CHCOOH}CH3CH(CH3)C(Cl)=CHCOOH
CH3CH=C(Cl)CH(CH3)COOH\text{CH}_3\text{CH}=\text{C(Cl)CH}(\text{CH}_3)\text{COOH}CH3CH=C(Cl)CH(CH3)COOH
CH3C(Cl)=C(CH3)CH2COOH\text{CH}_3\text{C(Cl)}=\text{C}(\text{CH}_3)\text{CH}_2\text{COOH}CH3C(Cl)=C(CH3)CH2COOH
