In the Summer After Your First Year at Law School

In the summer after your first year at law school, you begin an internship at a Texas law firm called "Execution Stoppers." As you discerned from their name, they specialize in keeping accused criminals off death row. On your first day at the firm, they ask you to write a memo summarizing their three easiest cases of the month. Case 1 involves a 17 year-old boy who is accused of felony murder, a capital offense in that state. Case 2 involves an accused murdered whose IQ score is 62. Case 3 involves an individual who raped and murdered a child. Answer the following questions about the report you will craft to summarize these cases.
-Assume that the state of Texas has established a standard that defines mental retardation as having an IQ score below 70. Based on this information, the client in Case 2:

A) can be executed only if his crime evinces certain "aggravating factors"
B) cannot be executed, as per Supreme Court precedent
C) can be executed as long as he is over the age of 18
D) can be executed if his crime involved at least one concurrent felony
