'Provides nutrients to the ACL' is not a function of the meniscus.
The meniscus is a C-shaped piece of tough with rubbery cartilage that acts as a shock absorber between the shinbone and the thighbone. It can be torn if you suddenly twist your knee while bearing weight on it.
The function of meniscus include- they act as shock absorbers and stabilize the knee. The meniscus act to disperse the weight of the body and reduce friction during movement. The menisci increase stability for femorotibial articulation, absorb shock, provide lubrication and nutrients to the knee joint.
Thus, the anterior cruciate ligament (ACL) of the knee receives its nutrition from a direct vascular supply, so the meniscus cannot provide nutrients to the ACL.
Hence, option B is correct.
