Main Answer:
The product of the given nuclear reaction
Mn (positron emission) is C.

Therefore, the correct answer is C.

Step-by-step explanation:
In a positron emission reaction, a proton is converted into a neutron, and a positron is emitted. The given reaction
Mn (positron emission) involves the transformation of manganese-50 with 25 protons into an isotope of chromium. Specifically, the positron emission results in the loss of a proton, converting manganese-50 into chromium-50 with 24 protons. This leads to the formation of
.
Positron emission is a type of radioactive decay where a proton is transformed into a neutron, and a positron is emitted to conserve charge. In this case, the original manganese isotope undergoes this decay process, resulting in a new chromium isotope with one less proton.
Understanding nuclear reactions is crucial in fields such as nuclear physics and nuclear medicine. Positron emission, in particular, plays a significant role in medical imaging techniques like positron emission tomography (PET) scans.
In conclusion, the correct product of the given nuclear reaction is
, as the positron emission transforms manganese-50 into chromium-50 with one less proton.
Therefore, the correct answer is C.
