A. Internal oviparous
B. Internal and viviparous
C. External and oviparous
D. External and viviparous

Explanation

To answer the question "Amphibians show_______ fertilization and are______," we can follow these steps:

### Step 1: Understand the Reproductive Method of Amphibians
Amphibians are known for their unique reproductive strategies. They typically reproduce by laying eggs in water, which is a key characteristic of their life cycle.

### Step 2: Identify the Type of Fertilization
Amphibians generally exhibit **external fertilization**. This means that the male and female gametes (sperm and eggs) are released into the external environment (usually water) where fertilization occurs outside the female's body.

### Step 3: Determine the Mode of Development
Amphibians are primarily **oviparous**, meaning they lay eggs that develop outside the mother's body. The eggs hatch into larvae (like tadpoles), which eventually metamorphose into adult amphibians.

### Step 4: Fill in the Blanks
Based on the information gathered:
- Amphibians show **external** fertilization and are **oviparous**.

### Final Answer:
Amphibians show **external** fertilization and are **oviparous**.
