Which of the following kingdoms contains multicellular organisms that ingest their food ?
(a) Protista
(b) Animalia
(c) Plantae
(d) Fungi

Options

A. Protista
B. Animalia
C. Plantae
D. Fungi

Explanation

To solve the question, "Which of the following kingdoms contains multicellular organisms that ingest their food?" we need to analyze each of the provided options:

1. **Protista**: This kingdom primarily consists of unicellular organisms. While there are some multicellular forms, they do not primarily include multicellular organisms that ingest food. Therefore, this option is not correct.

2. **Animalia**: This kingdom is known for containing multicellular organisms that are heterotrophic, meaning they obtain their food by ingestion. Animals do not produce their own food; instead, they consume other organisms or organic matter. Hence, this option is correct.

3. **Plantae**: This kingdom consists of multicellular organisms that are primarily autotrophic, meaning they produce their own food through photosynthesis. Therefore, this option is not correct.

4. **Fungi**: While fungi are multicellular, they are primarily saprophytic, meaning they absorb nutrients from dead and decaying matter rather than ingesting food. Thus, this option is also not correct.

Based on this analysis, the correct answer is:
**(b) Animalia**
