Best Answer Explained in Below-:

The term "omnivorous" derives from the Latin words "omnivorus," where "omnis" means "all" and "vorare" means "to eat." Therefore, omnivorous creatures have a diverse diet that includes both plant and animal matter. This characteristic is essential for many species, including humans, as it allows them to obtain a variety of nutrients necessary for survival.

The other options—eating only fruits, only meat, or only grassed plants—describe specific feeding habits associated with herbivores (plant-eaters), carnivores (meat-eaters), and specialized herbivores (like grazers), respectively. These categories do not encompass the full dietary range that omnivores are capable of consuming.

Being omnivorous offers adaptability in food sources, which can be beneficial in changing environments or when certain food resources are scarce. Hence, the correct answer to the definition of "omnivorous" is indeed B) eating all types of food, as it accurately captures the broad and inclusive nature of an omnivorous diet.
