cis- and trans-1-tert-butyl-4-chlorocyclohexane are each treated with $\mathrm{NaOEt}$ in ethanol. The tert-butyl group is so large that it stays equatorial in both. Which statement is correct?

1. AThe trans isomer reacts faster because its equatorial chlorine is less hindered
2. BThe cis isomer reacts much faster because its chlorine is axial and has anti-periplanar axial beta-hydrogens
3. CBoth isomers react at the same rate because both have the same leaving group
4. DThe trans isomer reacts faster because it can ring flip freely to put chlorine axial
