Compared with propene, which alkenes react faster with mCPBA under the same conditions?

Epoxidation is an electrophilic attack by the peracid oxygen, so electron-rich (more alkylated) alkenes react faster. 2-Methylpropene and but-2-ene are more substituted than propene. Ethene is less substituted and the strongly electron-withdrawing $\mathrm{CF}{}_3$ group deactivates 3,3,3-trifluoropropene. Options 1 and 2 are correct.
