Birch reduction gives tram product and Lindlar’s catalyst gives cis product

Q. BLindlar’sCatalyst​R−C≡C−RNa/NH3​​A A and B are geometrical isomers (R−CH=CH−R)−

A is trans, B is cis

A and B both are cis

A and B both are trans

A is cis, B is trans

Birch reduction gives tram product and Lindlar’s catalyst gives cis product

Q. $B Lindlar’s Catalyst R - C \equiv C - R N a / N H_{3} A$
A and B are geometrical isomers $(R - C H = C H - R) -$
