yes
benzene ring undergoes nitration
acidic HNO3 reacts with basic -NH2 group to form a salt

yes
but conditions for nitration i.e. h2so4 and temperature are missing, so why nitration is occuring?

there are 2 phenolic hydroxyl groups

the OH groups attached to the benzene rings are activating groups. the lone pair on the O atom overlaps with the pi ring, increasing electron density in the ring and attracting electrophiles. the ring is more reactive. https://www.chemguide.co.uk/organicp...ackground.html

Thank you. It means OH as in phenol doesnt need specific conditions like benzene does?

Yes. Phenol will react with dilute HNO3 at rtp while benzene reacts with conc H2SO4 + conc HNO3 at temperatures 50-60 degrees celsius for mononitration
