Alternate approach - test each statement against the core definition of IPM:
Integrated Pest Management, by definition, combines multiple control tactics while deliberately optimising (not eliminating) chemical use - so pesticide-use management is very much a core, integral component of IPM, meaning Statement (I), which denies this, does not hold and is false.
One of IPM's stated goals is to make pesticide application more precise and judicious - i.e. to refine when, how much, and which pesticide is applied, based on monitoring and thresholds.
Reading Statement (II) as phrased in the question, it is assessed as holding true in this question's context, so a false first statement paired with a true second statement identifies the matching option.
