Which structure corresponds to the IUPAC name 3-Ethyl-2-hydroxy-4-methylhex-3-en-5-ynoic acid?

To decode the name:Parent chain: Hexanoic acid (6 carbons, principal group $-\text{COOH}$ at position 1).Substituents: 2-hydroxy, 3-ethyl, 4-methyl.Unsaturation: 3-en (double bond at C3), 5-yn (triple bond at C5).Structure: ${\text{C}}_6(\text{yn})\equiv {\text{C}}_5-{\text{C}}_4({\text{CH}}_3)={\text{C}}_3({\text{C}}_2{\text{H}}_5)-{\text{C}}_2(\text{OH})-{\text{C}}_1\text{OOH}$ Simplified: $\text{HC}\equiv \text{C}-{\text{C(CH}}_3{\text{)=C(C}}_2{\text{H}}_5\text{)-CH(OH)COOH}$.
