Imagine the graph of function the \(f(x)=\sin(x).\) The domain of this function is the set of all real numbers \(R.\)

Consider the three sets

- \(A=\left\{ x\in \mathbb R|\sin(x)=-1 \right\}\)
- \(B=\left\{ x\in \mathbb R|\sin(x)=0 \right\}\)
- \(C=\left\{ x\in \mathbb R|\sin(x)=1 \right\}.\)

Which of them has the largest cardinality?
