What percentage of soybeans planted are genetically enhanced varieties?
A
74
B
90
C
15
D
30
Explanation: 

Detailed explanation-1: -In fact, the majority of soybeans (more than 90%) grown in the U.S. are bioengineered. These beans typically have herbicide-resistant genes inserted into their genetic structure so that farmers can use herbicides to destroy invasive weeds without harming the soybean plant.

Detailed explanation-2: -Currently, over 90 percent of corn, cotton, and soybean acreage in the United States is planted with genetically engineered (GE) seeds. Most of these GE seeds are either herbicide tolerant (HT) or insect resistant (Bt).

Detailed explanation-3: -These crops, commonly called “Roundup Ready”, have become ubiquitous in American agriculture with 93% of soybeans, 82% of cotton, and 85% of corn planted engineered to be glyphosate resistant.

Detailed explanation-4: -The top GM crop grown in 2015 was soybean (92.1 MHa), followed by maize (53.6 Mha), then cotton (24 Mha) and oilseed rape (canola) (8.5 Mha) (Figure 4). This represents 83% of the world production of soybean, and 75% of production of cotton.
