D Correct answer
Explanation

Microarray gene chips can simultaneously analyze expression patterns of thousands of genes, making them useful for screening for mutations leading to cancer (by detecting characteristic expression changes) and identifying carriers of genetic diseases (by profiling disease-associated expression signatures). They cannot identify behavioral traits, which are complex and multifactorial.
