Assertion: \( \int \frac{\mathrm{dx}}{\mathrm{x}^{3} \sqrt{1+\mathrm{x}^{4}}}=\frac{-1}{2} \sqrt{1+\frac{1}{\mathrm{x}^{4}}}+\mathrm{C} \)
P
Reason: For integration by parts, we have to follow ILATE rules
(1) Both assertion and reason are correct and reason is the correct explanation for assertion
(2) Both assertion and reason are correct and reason is not the correct explanation for assertion.
(3) Assertion is true but the reason is false.
(4) Both assertion and reason are false.
