The correct answer is C. Mysterious
Explanation:
In texts, it is common the meaning of an unknown word such as "inscrutable" can be guessed based on the context of the word. In the case presented the word "inscrutable" is used to describe the house a child is drawing, considering most children do not have impressive skills to draw, it can be inferred the house of the child is being described by the author as difficult to understand, and therefore the word "inscrutable" acts as a synonym of mysterious, puzzling or incomprehensible rather than impressive, beautiful or organic.
