Answer

Explanation:

Step1: Recall isotope - related definitions

Isotopes of an element have the same atomic number ($Z$). Indium has an atomic number $Z = 49$ from the periodic table. Also, $A=N + Z$, where $A$ is the mass - number and $N$ is the number of neutrons.

Step2: Analyze the first option

For $Z = 49,A = 113$, since $Z = 49$ (the atomic number of indium), this could be an isotope of indium.

Step3: Analyze the second option

For $N = 64,Z = 49$, since $Z = 49$ (the atomic number of indium), this could be an isotope of indium. We can also calculate $A=N + Z=64 + 49=113$.

Step4: Analyze the third option

First, use $A=N + Z$. Given $N = 61,A = 113$, then $Z=A - N=113 - 61 = 52\neq49$, so this is not an isotope of indium.

Step5: Analyze the fourth option

First, use $A=N + Z$. Given $A = 110,N = 49$, then $Z=A - N=110 - 49 = 61\neq49$, so this is not an isotope of indium.

Answer:

$Z = 49,A = 113$; $N = 64,Z = 49$
