The _______ function computes the time (in seconds) needed to execute

1.	The _______ function computes the time (in seconds) needed to execute an expression.(a) system.timedeb()(b) system.time()(c) system.datetime()(d) system.deb()This question was posed to me in an online interview.My doubt is from R Profiler in division Profiling, Simulation and Data Analysis of R Programming
Answer» CORRECT choice is (B) system.time() Explanation: They system.time() function takes an ARBITRARY R expression as input and returns the amount of time taken to evaluate the expression.
