The major product formed in the following reaction is
  

The correct answer is option 1.

Concept - 
​The reagent H₂ Palladium in presence of calcium or barium sulphate salt is reffered as lindlard catalyst it is often poisened with pyridine or quinoline.

• The lindlard catalyst is used for hydrogenation of alkynes to alkene.
• It generates a cis alkene.

Explanation -

•  As, the above reaction is taking place at 1 atm so only one of the alkyne will get converted.
• Now, according to the chemoselectivity the alkyns next to SiMe₃ Will not get reduced as Si is larger in size and wil act as soft center. 
• Hence, the another alkyne gets converted to cis alkene

Conclusion:-

So, The major product formed in the following reaction is option 1.
