Answer

Answer:

B. Zirconium - 93

Explanation:

Step1: Identify element by protons

The number of protons determines the element. 40 protons means the element is zirconium (Zr).

Step2: Calculate new neutron number

Initial 51 neutrons, 2 added. New neutron number is $51 + 2=53$.

Step3: Calculate mass number

Mass number = protons + neutrons. So, $40+53 = 93$. The isotope is Zirconium - 93.
