Pls help with this question

be right angle because of angle BDC: Angle of straight line is always 180 degrees. Now we have two angle measures of triangle BOD, as we know that sum of internal angles of a triangle is 180 degrees, so we have one angle measure of 46 and second is 90. Now 46+90+x=180, x=44, so angle OBD is 44 degrees. Now we can tell that which side is greater by looking at opposite angle to that side. 90>46>44 i.e; OB>BD>OD. So side BD is greater. Answer is B.
