Answer: C

Neural networks can be used to attack problems that require
consideration of numerous input variables, They are capable
of capturing relationships and patterns often missed by
other statistical methods. Neural networks will not discover
new trends. They are inherently nonlinear and make no
assumption about the shape of any curve relating variables
to the output. Neural networks will not work well at solving
problems for which sufficiently large and general sets of
training data are not obtainable.
