All the notations used in statemnt I and statement II are usual.
Statement I In triangle ABC, if `(cos A)/(a )=(cos B)/(b)=(cos C)/(c).` then value of `(r_(1)+r_(2)+r_(3))/(r)` is equal to 9.
Statement II If `Delta ABC:(a)/(sin A) =(b)/(sin B) =(c)/(sin C)=2R,` where R is circumradius.

A

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

B

C

Statement I is correct but Statement II is incorrect

D
