The correct answer is C. Manuel says he will take the suggestion under consideration
Step-by-step explanation:
Being a leader implies you direct actions that are necessary to achieve a specific goal. In this process, it is common alternative ideas emerge from people that are part of a team, these should be considered by the leader and integrated if they contribute positively to the process. Additionally, a leader needs to communicate assertively, which means being honest and defending own ideas without offending people or considering other people's ideas are useless.
According to this, Manuel should say he will consider the suggestions of his colleague because in this way as a leader he listens to other members of the team and integrates their ideas if these contribute to the process. Also, this shows assertive communication because he is honest without offending others or telling them their ideas are not good.
