From the question we can say,

Total no.of students who attended the exam = 450

Total no.of students who failed in all the three subjects =60

The rest of the students (the students other than the 60 students who failed in all the three subjects) have passed in atleast one of their subject.

So,

Total no.of students who passed in atleast one subject

=Total no.of students - Total no.of students who failed in all subject

=450 - 60

=390

So, the answer is 3).390
