Final Answer :
B
Explanation :
The correct expansion using the Binomial Theorem involves each term having a combination of xxx and (−2y5)(-2y^5)(2y5) raised to powers that sum to 4, and coefficients determined by the binomial coefficients (4k)\binom{4}{k}(k4) , where kkk is the term number. The powers of −2y5-2y^52y5 increase, resulting in the powers of yyy being multiplied by 5 for each term, and the negative sign leads to alternating signs when raised to even/odd powers.
