(a)
Interpretation: The major stereoisomer formed when the given
Concept introduction: In an elimination reaction, the major stereoisomer formed in the one which is most stable. In general, trans isomer is more stable than cis isomer as the substituents are attached far apart from each other causing less steric hindrance.
