Final answer:
Detergent antiseptics inactivate viruses mainly by breaking down the viral envelope, and they are designed to target the protective lipid layer surrounding some viruses.
Step-by-step explanation:
Detergent antiseptics inactivate viruses primarily by breaking down the viral envelope. This method disrupts viruses by attacking the protective lipid layer that encases some types of viruses, particularly enveloped ones. Although there can be secondary effects such as disrupting the viral replication process or inhibiting viral attachment to host cells, the primary action is the breakdown of the viral envelope. The 'envelope' is essentially a lipid membrane taken from the host cell by the virus as it exits after replication, aiding in both its protection and infection process.
As for the substance suitable for use on tissues for microbial control to prevent infection, the correct choice would be B. antiseptic. Unlike disinfectants, which are used for inanimate objects, antiseptics are suitable for application on living tissues to prevent microbial infections.
