ધારો કે $f:[0,1] \rightarrow [0, \infty)$ એક સતત વિધેય છે જેથી $\int_0^1 f(x) dx = 10$ થાય. નીચેનામાંથી કયું વિધાન હંમેશા સાચું નથી?

  • A
    $\int_0^1 e^{-x} f(x) dx \leq 10$
  • B
    $\int_0^1 -\frac{f(x)}{(1+x)^2} dx \leq 10$
  • C
    $-10 \leq \int_0^1 \sin(100x) f(x) dx \leq 10$
  • D
    $\int_0^1 f(x)^2 dx \leq 100$
