Step 1: Use the sentence structure
The passage lists three names, Angora, Saanen and Alpine, and calls them exotic breeds of goat. So the animal word attached to this list is goat.
Step 2: Cross-check with what you know
Saanen and Alpine are famous exotic dairy goats. Angora goats are raised for mohair. All three are goats, so the list agrees.
Step 3: Remove cattle and buffalo
Exotic cattle are Jersey and Holstein Friesian, and buffaloes have no exotic breed like Angora. Options (1) and (2) go.
Step 4: Remove sheep
Merino and Rambouillet are the exotic sheep. Option (3) does not fit the name Angora.
Step 5: Choose goat
Only option (4) matches both the passage and general knowledge.
Final Answer:
Angora belongs to goats, so the answer is option (4).
\[ \boxed{\text{Option (4)}} \]
