Answer:

Option A. ⁰₋₁β

Explanation:

Let the unknown be ʸₓA

Thus, the equation given becomes:

⁹⁸₄₃Tc —> ⁹⁸₄₄Ru + ʸₓA

Next, we shall determine the value of x, y and A in order to obtain the answer to the question. This can be obtained as follow:

43 = 44 + x

Collect like terms

43 – 44 =

–1 = x

x = –1

98 = 98 + y

Collect like terms

98 – 98 = y

0 = y

y = 0

ʸₓA => ⁰₋₁A => ⁰₋₁β

Thus, the complete equation is

⁹⁸₄₃Tc —> ⁹⁸₄₄Ru + ⁰₋₁β

The missing item is ⁰₋₁β
