Explanation:
<em>The field of </em><em>recombinant DNA technology</em><em> is a thoroughly modern discipline that has led to new ways to treat infectious diseases.</em>
<u>Recombinant DNA technology involves the process of combining DNA of different organisms and inserting such in a host organism in order to elicit desirable genetic characters that could be of value to different fields in science.</u>
The fields in which recombinant DNA technology has found applications include agriculture, medicine, and industrial productions. With this technology, new drugs and methods of treating diseases have been developed in the area of medicine, disease-resistant crop varieties have been developed in agriculture, and important chemicals for production have been developed in industries.
<em>Correct option:</em><em> A</em>
