Final answer:
The questions explore the relationships between angles, including complementary and vertical angles. However, without more context, the specific relationships of 'Bis' and 'Care' to given angles cannot be discerned with certainty.
Step-by-step explanation:
The question involves concepts related to angles, particularly complementary angles, vertical angles, and the calculations of angles in a vector context. When it mentions that 'angle A is 48°', it seeks to determine the relationship between angle A and other angles, possibly in the context of geometry or vector addition. However, without additional information, it is not possible to definitively conclude what Bis and Care refer to or their relationships to angle A.
Regarding the portion 'If angle B is 140°', it also explores the relationships between angles. Complementary angles sum up to 90°, and thus angle B cannot have a complementary angle in this case. Vertical angles are equal, so this option could be valid if angle B has a vertical counterpart. Option C is incorrect because if angle B is 140°, then it cannot be equal to 40°. Option D is a general concept that opposite angles in an intersection of two straight lines are the same.
