Three sides of a triangle have the equation `L_i = y - m_i x = 0` , I = 1, 2, 3. Then `L_1L_2 + lambdaL_2L_3 +_ muL_3L_1 = 0`
(where `lambda ne 0, mu ne 0`). Is the equation of the circumcircle of the triangle if

A

`1 + lambda + mu = m_1m_2 + lambdam_2m_3 + lambda m_3m_1`

B

`m_1(1+mu)+m_2(1+lambda)+m_3(mu+ lambda) = 0`

C

`1/m_3 + 1/m_1 + 1/m_2 = 1 + lambda + mu`

D
