Answer:
B). Industry vs. Inferiority.
Step-by-step explanation:
'Industry versus Inferiority' is categorized as the fourth stage of Psycho-social development out of the eight stages. This stage primarily occurs between the age of 6 to 11 years in which the child learns to be more productive. At this stage, the child tends to show acceptability towards the evaluation of their selves as they develop self-esteem is they measure-up and feel inferior or subordinate when they fail to do so.
In the given example, Manuel's attribute reflects that he is in this 'industry vs inferiority' stage of psychosocial development theory proposed by Erikson as he feels 'pride in his skills' which mirrors the development of 'self-esteem' and he has become more 'acceptable' as 'he works hard at them and believes that he is good' in those skills which reflects his 'industrious' attitude as he knows that failing it would lead to a sense of 'inferiority'. Therefore, option B is the correct answer.
