From the word lettered A to E , choose the word that best completes the sentence.
The building ... because of weak structural foundation
Answer Details
The word that best completes the sentence is "collapsed".
The sentence is asking about a possible reason for a building's failure, and the word "collapsed" fits the context perfectly. When a building collapses, it means that the entire structure falls down, often due to weak structural foundation or other serious structural problems.
The other options (tumbled, succumbed, caved, and somersaulted) are less appropriate because they do not accurately convey the specific idea of a building falling down due to structural issues. Tumbling, succumbing, caving, and somersaulting all suggest movement or change, but not necessarily the kind of catastrophic failure that would occur if a building collapsed.
