An organic compound (A) `(C_(10)H_(20))`on reductive ozonolysis gives `2-` methyl butanal. Based on this information, answer the following question.
If the stereochemistry about the double bond in (A) is cis, the total number of stereoisomers for (A) is :

Options

A. `2,` pair of enantiomers.
B. 3, one pair of enentiomers and one meso form `(` optically inactive due to the presence of centre of symmetry `)`.
C. 3, one pair of enenctiomers and one meso form `(` optically inactive due to the presence of plane of symmetry `)`.
D. 2, both optically inactive due to the presence of both centre and plane of symmetry.

Answer

c

Explanation

If compound `(a)` is `cis,` we get diastereomers, `(III)` and `(VI), (III)`is meso `(O.I.A.)` due to plane of symmetry. `(IV)` is `O.A.(` two enantiomers `).` Total stereoisomers when `(A)` is `cis =3`
