Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
For polynomial equation with rational coefficients irrational roots occur in pairs
Given 32 then 3+2,3+2,32 are remaining roots.
Sum of roots =0
Product of roots (3+2)(32)(3+2)=+1
x410x2+1=0 has 32,3+2,3+2,32
Both assertion and reason are correct
