Let `f(x),g(x),h(x)` and `R(x)` be four functions `f(x)=e^({2x})`
where {.} represents fraction function.
`g(x)=|sin pi x|+|cos pi x|+tan pix, h(x)=e^({x})+sin(4pix),R(x)=sqrt(sin^(2)4pix)`
Column I: contains functions
Column II: contains domain of the functions
Column III: contains fundamental period of the function.

Options

A. (III)(ii)(R)
B. (III)(i)(R)
C. (IV)(i)(R)
D. (IV)(i)(P)
