d) botulism

Explanation:

Droplet transmission occurs when bacteria or viruses travel on relatively large respiratory droplets that people sneeze, cough, drip, or exhale.

Many common infections can spread by droplet transmission in at least some cases, including: Common cold, Diphtheria, Fifth disease (erythema infectiosum), Influenza, Meningitis, Mycoplasma, Mumps, Pertussis (whooping cough), Plague, Rubella, Strep (strep throat, scarlet fever, pneumonia), Tuberculosis, measles.

Frequent hand cleansing, especially with instant hand sanitizers, can help prevent droplet transmission.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
