<ABC

C) ∠ABC

Step-by-step explanation:

∠ABC is a wrong classification of the angle presented because that would imply angle B is the included angle, but it's really angle A that's included (or angle 1). Therefore, the rest of the options are correct and C is the wrong one.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
