Which of the following statements is false?

a) A concept called threads enables the operating system to run parts of an app
concurrently. Though all of these tasks can make progress concurrently, they may do so
by sharing one processor core.
b) With multicore processors, apps can operate truly in parallel on separate cores,
possibly increasing the app’s performance substantially.
c) Parallelizing apps and algorithms to take advantage of multiple cores is difficult and
highly error prone, especially if those tasks share data that can be modified by one or
more of the tasks.
d) A benefit of functional programming is that you can easily ask the library to perform a
task with parallel processing to take advantage of a processor’s multiple cores. This is the
purpose of CLINQ (Concurrent LINQ)—an implementation of the LINQ to Objects
extension methods that parallelizes the operations for increased performance.
