Step 1
B. Strange particles are always created in pairs.
Answer
In particle physics, strange particles, which contain strange quarks, are indeed always produced in pairs in any reaction. This occurs due to the conservation of quantum numbers, particularly strangeness. This statement is correct and is a key principle in the understanding of particle interactions.
