Dear Student,

​14. The total number of conformation of ethane is infinite as the rotation around C-C bond is continuous. 
Hence, correct answer is (d)

16. Maleic acid and fumaric acid are geometrical isomers as they differ in the arrangement of groups. 
Hence, correct answer is (b)

18. Meso stereoisomers have plane of symmetry. Symmetry is present in (d) compound as passing a plane will bisect the molecule into two identical halves. 
Therefore, correct answer is (d)
