B) Many of the observations regarding Exposure A and Disease X have been replicated repeatedly.
C) Prevalence of Exposure A in patients with Disease X is 90% to 100%.

Final Answer :
E
Explanation :
All of the answers suggest causal relationship between exposure and outcome."Exposure A is clearly linked to mediator M.Approximately 11% of mediator M patients will go on to have Disease X over a 10-year period" indicates the temporal relationship."Many of the observations regarding Exposure A and Disease X have been replicated repeatedly" indicates replication of the findings."Prevalence of Exposure A in patients with Disease X is 90% to 100%" means there is specificity of the association."Eradication of Exposure A heals Disease X at the same rate as other treatment of choice" is a cessation of exposure.All of the answers indicate that Exposure A is a causative agent for Disease X.
