Correct option is B
Explanation of the Correct Answer: · "They share rent of the house equally" requires "the" before "house" because it refers to a specific house known to the speaker and listener.
Why Are the Other Options Incorrect? · (a) "He lives somewhere in southern Germany." → No article needed before "southern Germany" as geographical regions don’t take articles.
· (c) "She is ignorant of her social standing." → No article required before "social standing" as it is an abstract noun.
· (d) "She has an abundance of cake at home." → "An" before "abundance" is correct; no additional article needed.
Thus, the correct answer is: (b) "They share rent of the house equally."
