A different way to check this kind of question is to read each numbered part on its own first for spelling, and only then check the whole combined sentence for grammatical agreement.
Reading the parts individually and combining them into "I am fully aware that my wife is one of those who are totally committed to the family and its well-being" shows that part 3 is the only one requiring correction.
Hence, the correct answer is 3 is incorrect.
A different way to check this sentence is to compare it against a short list of causative verbs and their required verb forms, rather than examining each part in isolation.
Checking the causative-verb rule shows that only part 1 violates it, since "make" must be followed directly by the bare infinitive "wait."
Hence, the correct answer is 1 is incorrect.
