The coefficient of

x^{53}

\sum\limits_{{r=0}}^{100}{ }^{100} C_r(x-3)^{100-r} 2^r

View answer and explanation

Correct option: C

{ }^{-100} C_{53}

Option C (

{}^{-100} C_{53}

) is correct because the given expression simplifies to (x-1)¹⁰⁰, and the coefficient of x⁵³ is found using the binomial theorem.
