Option 1: Coffee is a plantation crop. Plantation crops are crops that are grown on large-scale plantations and require extensive labor and management. Coffee plantations are widespread in countries such as Brazil, Colombia, and Ethiopia.

Option 2: Sugarcane is also a plantation crop. It is grown in tropical and subtropical regions and is used for the production of sugar, as well as biofuels such as ethanol.

Option 3: Wheat is not a plantation crop. Wheat is a cereal crop that is typically grown in temperate regions. It is cultivated in small to medium-sized farms rather than large-scale plantations. Wheat is an important staple food and is grown in countries such as the United States, China, and Russia.

Option 4: Rubber is another example of a plantation crop. It is grown primarily in regions with a tropical climate, such as Southeast Asia and Africa. Rubber is obtained from the latex of rubber trees, which are grown in large plantations.

Therefore, option 3 (Wheat) is the correct answer as it is not a plantation crop.
