Statement I In `a DeltaABC, sum (cos ^(2)""(A)/(2))/(a )` has the value equal to `(s^(2))/(abc).`
Statement II in `a Delta ABC, cos ""A/2=sqrt(((s-b)(s-c))/(bc))`
`cos ""(beta)/(2)=sqrt(((s-a) (s-c))/(ac)), cos ""c/2= sqrt(((s-a)(s-b))/(ab))`

Options

A. If statement -1 is true, statement –II is true, statement –II is a correct explanation for statement-I
B. If statement –I is true, statement –II is true, statement –II is not a correct explanation for statement –I
C. If statement –I is true, statement –II is false
D. If statement –I is false, statement –II is true

Answer

C
