Suppose a Student class has the following instance variables:

$-$ id: int

$-$ name: String

Now, consider the following assumptions:

s$1$ and s$2$ are both Student objects.

s$1$ and s$2$ are not null.

$($s$1==$ s$2)$ evaluates to true in a Java program.

What is true about s$1$ and s$2$ under these assumptions?

Question options:

A$.$ s$1$ is a deep copy of s$2$

B$.($s$1.$id $==$ s$2.$id$)$ && $($s$1.$name $==$ s$2.$name$)$

C$.$ s$1$ and s$2$ both reference the same place in memory

D$.$ B and C

E$.$ A$,$ B$,$ and C
