Correct option is C)

The number of stereoisomers possible for H

3

C−CH(OH)−CH(OH)−CH

3

is 3.

H

3

C−CH(OH)−CH(OH)−CH

3

has two chiral carbon atoms and is symmetrical, therefore n=2

Number of d and l isomers 2

n−1

=2

2−1

=2

Number of meso forms 2

n/2−1

=2

2/2−1

=2

2

=4

Total number of stereoisomers =2+4=6

Hence, the correct option is C
