exam question

an old exam question from my biochem class:

While of the following statements is FALSE? DNA chips:
a) can be used for detection of single nucleotide polymorphisms and for measuring the levels of mRNAs.
b) refer to DNA adhered to a surface that is available for base pairing with a complementary probe.
c) can have hundreds of thousands of unique sequences on a single chip slightly greater than 1 square centimeter.
d) have been used to show that different cancer cells have distinct patterns of gene expression.
e) are now the currency of preference at Las Vegas casinos.

i hate when they write such ridiculously obvious questions. i'd rather that they write a really easy question that is not so obvious so i can at least feel good about myself when i get it right.

o yeah, the answer is "e".
