Final answer:
The particle emitted during beta decay as represented by the notation ^14 v6 C (beta emission) is a Beta particle.
Step-by-step explanation:
Beta (B) decay is the emission of an electron from a nucleus. In the case of ^14 v6 C (beta emission), a beta particle is emitted. A beta particle is a high-speed electron emitted from the nucleus of an atom during radioactive decay. Therefore, the correct answer is B) Beta particle.
