\end{tabular}

A. [tex]$X$[/tex] and [tex]$Y$[/tex]
B. [tex]$X$[/tex] and [tex]$Z$[/tex]
C. [tex]$Y$[/tex] and [tex]$Z$[/tex]
D. [tex]$X, Y$[/tex], and [tex]$Z$[/tex]
E. There are no isotopes among these atoms

Let's carefully examine whether the given atoms are isotopes of each other.

Isotopes are atoms that have the same atomic number but different mass numbers.

1. Comparing atoms [tex]\(X\)[/tex] and [tex]\(Y\)[/tex]:
- Atomic number of [tex]\(X\)[/tex] is 10.
- Atomic number of [tex]\(Y\)[/tex] is also 10.
- Both [tex]\(X\)[/tex] and [tex]\(Y\)[/tex] have different mass numbers (20 and 21, respectively).

Since [tex]\(X\)[/tex] and [tex]\(Y\)[/tex] have the same atomic number but different mass numbers, they are isotopes of each other.

2. Comparing atoms [tex]\(X\)[/tex] and [tex]\(Z\)[/tex]:
- Atomic number of [tex]\(X\)[/tex] is 10.
- Atomic number of [tex]\(Z\)[/tex] is 11.

Since [tex]\(X\)[/tex] and [tex]\(Z\)[/tex] have different atomic numbers, they are not isotopes of each other.

3. Comparing atoms [tex]\(Y\)[/tex] and [tex]\(Z\)[/tex]:
- Atomic number of [tex]\(Y\)[/tex] is 10.
- Atomic number of [tex]\(Z\)[/tex] is 11.

Since [tex]\(Y\)[/tex] and [tex]\(Z\)[/tex] have different atomic numbers, they are not isotopes of each other.

To summarize, from the given information:
- [tex]\(X\)[/tex] and [tex]\(Y\)[/tex] are isotopes of each other.
- [tex]\(X\)[/tex] and [tex]\(Z\)[/tex] are not isotopes.
- [tex]\(Y\)[/tex] and [tex]\(Z\)[/tex] are not isotopes.

Therefore, the correct answer is:

A. [tex]\(X\)[/tex] and [tex]\(Y\)[/tex]
