Class 12 Maths · Relations And Functions · Mcq Single Correct #50

Let \(A=\{1,2,3\}\), \(B=\{a,b,c\}\), and \(f=\{(1,a),(2,b),(P,c)\}\) be a function from \(A\) to \(B\). For \(f\) to be one-one and onto, \(P=\)

✅ Step-by-Step Solution

Final Answer: Option (C): 3
  1. The third input must be the remaining element 3, so each input has exactly one image and all three outputs occur.
