A is grammatically incorrect at A. B suits A. so, A-B can be interchanged. Also, C and D are incorrect at their places. So, they also need to be interchanged. The many mutations that have so far been identified in RBD help the novel coronavirus avoid detection, but therersquo;s also a trade-off in that too many changes affect the efficiency with which the RBD can bind onto the human cell.
