In the following questions, a part of the sentence has been highlighted. Choose the most appropriate replacement from the given options. If no improvement is required, choose the option accordingly. During the intense debate, tensions began to rise, leading one participant to break away emotionally, revealing his vulnerability.

The sentence suggests: emotional vulnerability, loss of emotional control during tension. The correct phrasal verb should therefore mean: → emotional collapse. “Break down” means: → lose emotional control or become emotionally overwhelmed.
