For the following thermal $[2+2]$ cycloaddition reaction, the correct statement about Transition State (TS) and preference for endo product formation is 
(a)TS: $\pi 2 \mathrm{s}+\pi 2 \mathrm{s}$; Me > i-Pr > t-Bu
(b)TS: $\pi 2s + \pi 2a$; t-Bu > i-Pr > Me
(c)TS: $\pi 2s + \pi 2a$; Me > i-Pr > t-Bu
(d)TS: $\pi 2 \mathrm{s}+\pi 2 \mathrm{s} ; \mathrm{t}-\mathrm{Bu}>\mathrm{i}-\mathrm{Pr}>\mathrm{Me}$
