Consider the following statements `(A-C)` each with two blanks.
A. Animals like Hydra and jelly fis depict `ul((i))` symmetry whereas earthworm and leech show `ul((ii))` symmetry.
B. In `ul((iii))` and `ul((iv))` digestive tract has only single opening (mouth) and is said to be incomplete.
C. Trichinella (Trichina worm) is a cosmopolitan `ul((v))` parasite whereas Fasciola (live fluke) lives in the bile ducts of the liver of `ul((vi))`
Which one of the following options, correctly fills any two statements?

Options

A. (i)-bilateral, (ii)-radial
(v)-snail, (vi)-human
B. (iii)-Porifera, (iv)-Pisces
(v)-human, (vi)-sheep
C. (i)-radial, (vi)-bilateral
(iii)-Coelenterata, (iv)-Platyhelminthes
D. (iii)-Amphibia, (iv)-Annelida
(v)-mosquito, (vi)-human

Answer

To solve the question, we will fill in the blanks for each of the statements (A-C) step by step.

### Step 1: Analyze Statement A
**Statement A:** Animals like Hydra and jellyfish depict `ul((i))` symmetry whereas earthworm and leech show `ul((ii))` symmetry.

- **Blank (i):** Hydra and jellyfish belong to the phylum Coelenterata (now called Cnidaria) and exhibit **radial symmetry**.
- **Blank (ii):** Earthworm and leech belong to the phylum Annelida and exhibit **bilateral symmetry**.

**Filled Statement A:** Animals like Hydra and jellyfish depict **radial symmetry** whereas earthworm and leech show **bilateral symmetry**.

### Step 2: Analyze Statement B
**Statement B:** In `ul((iii))` and `ul((iv))` digestive tract has only a single opening (mouth) and is said to be incomplete.

- **Blank (iii):** Animals with an incomplete digestive system include **Cnidarians (Coelenterates)**.
- **Blank (iv):** Another group with an incomplete digestive system is **Platyhelminthes (flatworms)**.

**Filled Statement B:** In **Cnidarians** and **Platyhelminthes**, the digestive tract has only a single opening (mouth) and is said to be incomplete.

### Step 3: Analyze Statement C
**Statement C:** Trichinella (Trichina worm) is a cosmopolitan `ul((v))` parasite whereas Fasciola (liver fluke) lives in the bile ducts of the liver of `ul((vi))`.

- **Blank (v):** Trichinella is a cosmopolitan **intestinal** parasite.
- **Blank (vi):** Fasciola (liver fluke) lives in the bile ducts of the liver of **sheep**.

**Filled Statement C:** Trichinella (Trichina worm) is a cosmopolitan **intestinal** parasite whereas Fasciola (liver fluke) lives in the bile ducts of the liver of **sheep**.

### Final Summary of Filled Statements
- **Statement A:** Radial symmetry; Bilateral symmetry
- **Statement B:** Cnidarians; Platyhelminthes
- **Statement C:** Intestinal; Sheep
