According to Erikson, adolescents are in the stage of: 1. identity versus diffusion. 2. independence versus neediness. 3. intimacy versus isolation. 4. integration versus separation.

Option 1, identity versus diffusion.

Explanation:

The fifth stage of Erikson talks about the adolescent age where individuals have a confusion related to their identity and role with in the society. In this age group children generally face a conflict between their self-identity (likeliness of doing something which they like) and social responsibility enforced on them thereby ignoring their individual identity.  

For instance, a girl may like to dress like a boy and indulge in all manly activities but the society forces her to behave more like a girl

Hence, option 1 is correct
