Most animals are
(A) Haploid
(B) Diploid
(C) Heterotrophic
(D) Both B and C

Options

A. Haploid
B. Diploid
C. Heterotrophic
D. Both B and C

Answer

To solve the question, "Most animals are," we need to analyze each option provided:

1. **Understanding the options**:
- (A) Haploid: This refers to cells that have one set of chromosomes. Most animals are not haploid; they are typically diploid.
- (B) Diploid: This refers to cells that have two sets of chromosomes, one from each parent. Most animals are indeed diploid.
- (C) Heterotrophic: This means that organisms cannot produce their own food and must obtain it from other sources. Most animals are heterotrophic as they rely on other organisms for nutrition.
- (D) Both B and C: This option suggests that animals are both diploid and heterotrophic.

2. **Analyzing the characteristics of animals**:
- Most animals are multicellular and eukaryotic, which means they have complex cells with a nucleus.
- They are primarily diploid, meaning they have two sets of chromosomes (one from each parent).
- Animals do not produce their own food (they are heterotrophic) and depend on other organisms for sustenance.

3. **Conclusion**:
- Since most animals are both diploid and heterotrophic, the correct answer is (D) Both B and C.

**Final Answer**: (D) Both B and C
