The angle of a triangle ABC are in an arithmetic progression . The larger sides a,b satisfy the relation ` (sqrt(3))/(2) lt (b)/(a) lt 1 .` then the possible values of the smallest side are

A

` ( a+- ( sqrt(4b^(2)-3a^(2))))/(2a)`

B

` ( a+- ( sqrt(4b^(2)-3a^(2))))/(2b)`

C

` ( a+- ( sqrt(4b^(2)-3a^(2))))/(2c)`

D

` ( a+- ( sqrt(4b^(2)-3a^(2))))/(2)`
