单项选择题

Scientists in the US have created a new strain of mosquito that’s resistant to malaria, meaning it can’t then pass the disease onto humans. But their release into the wild is several years away.
Scientists say this is a key step on a long journey towards fighting the disease with genetically modified mosquitoes. The researchers used a single genetic tweak to interfere with the production of a molecule in the insect’s gut. Previous studies have attempted a similar approach, but this is the first time that scientists have completely blocked the development of the malaria parasite inside the mosquito. This rendered the insect unable to spread the disease. The ultimate aim is to release these malaria-resistant mosquitoes into the wild, but scientists will first need to work on more genetic trickery to give their insects a competitive advantage over their disease-spreading counterparts.
Which of the following description is INCORRECT().

A. The new strain of mosquito has been released into the wild.
B. Scientists have done similar researches before.
C. The new strain of mosquito cannot spread the disease.
D. This kind of mosquito is genetically modified.
