An inexperienced intern at the research group was writing a report to the National Cancer Institute and public health officials. The intern read the list provided by these hospitals in the Midwest which summarized the above data related to the characteristics of people who have a new CRC diagnosis, including a higher number of KRAS mutations. The intern concluded that the data showed that KRAS mutations were one of the risk factors for CRC. Do the data presented so far support the intern's conclusions? Why or why not?
a) Yes, because the data show a higher number of KRAS mutations in people with new CRC diagnoses.
b) No, because the data do not mention any correlation between KRAS mutations and CRC.
c) Maybe, more information is needed to determine if KRAS mutations are a risk factor for CRC.
d) Cannot be determined from the information provided.
