Answer: (A)

Verified step by step guidance

1. Step 1: Begin by understanding the key terms provided in the question. Each term represents a biological concept: Competition, Mutation, Speciation, and Symbiosis.
2. Step 2: Define 'Competition' in the context of biology. It refers to the interaction between organisms or species that vie for the same limited resources, such as food, water, or shelter, in a habitat.
3. Step 3: Define 'Mutation.' A mutation is a change in the DNA sequence of an organism, which can lead to genetic variation but is not directly related to the struggle for resources.
4. Step 4: Define 'Speciation.' Speciation is the evolutionary process by which new biological species arise, which is unrelated to the immediate struggle for survival in a habitat.
5. Step 5: Define 'Symbiosis.' Symbiosis refers to a close and long-term biological interaction between two different organisms, which can be mutualistic, commensalistic, or parasitic, and does not describe the struggle for resources.
