Answer:
Option A
Step-by-step explanation:
The reaction:
¹⁰B + ¹n → ⁷Li + ⁴He
Correspond to a boron neutron capture therapy, which is used for treating malignant tumors and extracutaneous melanomas.
In the reaction, the boron-10 captures the neutrons and undergoes nuclear fission to produce nuclei lithium-7 and alpha particles (nuclei ⁴He) than can kill the tumor cells.
Hence, the correct answer is option A) when boron-10 is struck by neutrons, it produces lithium-7 and an alpha particle.
