<h2>Answer:</h2>

Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.

<h3>Explanation:</h3>

Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
This bacterium is a soil bacterium which has no side effects on humans.
Due to use of this technology, the poisonous chemical insecticides are not used in crop production.

<h2>Answer is option "b"</h2>

Explanation:

Non-ionizing radiation is radiation that has a lower frequency, or longer wavelength, in the EMR spectrum. These frequencies range from that of power lines, radios, and cell phones, up to visible light. Non-ionizing radiation is not powerful enough to break the chemical bonds in molecules. In general, it is not harmful to human health as radiation per se, but could be harmful in terms of the transfer of heat energy. An example of an emitter of non-ionizing radiation is a microwave oven.
Non-ionizing radiation is less harmful because the rays carry much less energy. Radio waves, light, and even heat are examples of non-ionizing radiation. For the most part, these kinds of radiation do not cause any damage. However, ultraviolet light is a kind of non-ionizing radiation that can be harmful - it can cause mutations in DNA
Non-ionizing radiation is limited to the lower energy range electromagnetic radiation, which is more commonly known as light. However, the light we can see with our eyes, visible light, is only a small section of the electromagnetic radiation spectrum as seen here
Hence the right answer is option "b"
