Answer 1

The Correct Option is C

C1 inhibitor deficiency is associated with hereditary angioneurotic oedema Deficiencies in C1 C2 and C4 components are associated with systemic lupus erythematosus and other collagen vascular diseases Deficiency in C3 and its regulatory protein causes recurrent pyogenic infections Deficiency in C5 C6 C7 C8 and C9 components results in bacteremia mainly with Gram-negative diplococci and toxoplasmosis
