All animals are a. multicellular, heterotrophic, and diploid. b. multicellular, heterotrophic, and haploid. c. multicellular, autotrophic, and diploid. d. multicellular, autotrophic, and haploid.

The correct answer is option a, that is, multicellular, heterotrophic, and diploid.  

Animals refer to the multicellular eukaryotic species, which forms the biological kingdom Animalia. Animals exhibit many features, which distinguish them from other living species. The animals are multicellular and eukaryotic, unlike prokaryotic bacteria, and unlike protists that are eukaryotic but unicellular.  

The animals are heterotrophic, not like algae and plants that generate their own food. Almost all the animals make use of some kind of sexual reproduction. They are diploid and generate haploid gametes by the process of meiosis, the larger non-motile gametes are ova and the smaller motile gametes are spermatozoa.  

not sure but try c two haploid cells

explanation:

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
