Final answer:
Particles with strangeness can have or not have a strange quark, depending on the particle.
Step-by-step explanation:
Particles with strangeness do not necessarily always have a strange quark in them. While the presence of a strange quark is associated with strangeness, it is not a requirement for all particles. Some particles with strangeness can have multiple quarks, including strange quarks, while others can have no strange quark at all. Therefore, the answer is c) Depends on the particle.
