What happens when an atom of oxygen is subjected to external magnetic field?

(a) It is weakly attracted and loses magnetism on removal of field

(b) It is weakly attracted and does not lose magnetism on removal of field

(c) It is weakly attracted and domains align themselves in the direction of field

(d) It is not attracted

This question was posed to me during an interview.

I'm obligated to ask this question of P-Block Elements in portion P-Block Elements of Chemistry – Class 12

Right option is (a) It is weakly attracted and loses magnetism on removal of field

Easiest explanation: Oxygen atom is paramagnetic in nature. Meaning, on the application of an external magnetic field, it is slight attracted and loses magnetism on the removal of the field.
