Two C5H8 isomers undergo catalytic (Pt) hydrogenation to form the same C5H10 product. On ozonolysis followed by oxidative workup (H2O2), one isomer gave a C5 a cyclopentene and 1-pentyne b cyclopentene and 1-methylcyclobutene c 1-methylcyclobutene and 3-methylcyclobutene d cyclopentene and 3-methylcyclobutene cyclopentene and 1-methylcyclobutene

• A. cyclopentene and 1-pentyne
• B. cyclopentene and 1-methylcyclobutene
• C. 1-methylcyclobutene and 3-methylcyclobutene
• D. cyclopentene and 3-methylcyclobutene
