This is an Assertion/Reason type question, so we must evaluate both statements carefully before deciding how they relate.
Option a: Both the Assertion and Reason are true, and the Reason is a correct explanation of the Assertion. Here, the Assertion claims that smallpox has been eradicated from the world. This is true. The Reason states that antiviral agents that block replication were used to eradicate the virus. This is not accurate for smallpox eradication, since there was no successful antiviral drug that was the decisive factor in eradicating smallpox; the global eradication effort relied on vaccination and public health campaigns. Therefore, this option is false because the Reason is not a correct explanation.
Option b: Both the Assertion and Reason are true, but the Reason is not a correct explanation of the Assertion. While the Assertion is true, the Reason being true is incorrect because antivirals against smallpox were not the reason for eradication; vaccination achieved herd immunity and interruption of transmission. Thus, this option is false on the second clause.
Option c: The Assertion is true but the Reason is false. This says the disease has been eradicated — which is true for smallpox — and that the Reason (antiviral agents blocking replication) caused eradication — which is false, given vaccines were the key tool. Since one statement is true and the other is false, this option correctly characterizes the relationship between the two statements.
Option d: The Assertion is false but the Reason is true. The Assertion is not false, so this option is incorrect because it contradicts the known fact that smallpox has been eradicated. The Reason being true does not salvage this option.
Option e: Both the Assertion and Reason are false. This contradicts established historical evidence that smallpox eradication has been achieved and that antivirals were not the driving cause, so this option is false.

In summary, the falsehood lies in attributing eradication to antiviral agents, while the true element is that smallpox has been eradicated through vaccination efforts rather than antivirals. The correct characterization among the choices hinges on separating the factual eradication from the incorrect causal claim in the Reason.
