Viruses are nonliving complex chemical entities. They undergo inactivation and hence lose the ability to infect a host, with time. Concentration (expressed as 'median tissue culture infectious dose', TCID/ml, a unit used in expressing virus concentrations) vs. time plots of a corona virus on the surfaces of a paper currency note and a plastic currency note are shown below. Both these plots have two separate regions (shown by vertical lines in the plots), indicating two time zones. I. Paper currency note Viruses are nonliving complex chemical entities. They undergo inactivation and hence lose the ability to infect a host,

II. Plastic currency note Viruses are nonliving complex chemical entities. They undergo inactivation and hence lose the ability to infect a host,

The correct option/s among the following is/are

Options

AInactivation of the virus follows zero order kinetics in $1^{\text {st }}$ zone and first order kinetics in $2^{\text {nd }}$ zone
BThe rate of inactivation is independent of the surface material
CThe virus reacts with different chemical entities/substances in $1^{\text {st }}$ zone and $2^{\text {nd }}$ zone
DOn both the surfaces, at least $95 \%$ of the virus is inactivated within 10 h

Correct answer

D. On both the surfaces, at least $95 \%$ of the virus is inactivated within 10 h
