Sentence Correction (SC) | Re: Daniel Bernoulli derived the famous fluid equation

Hi Mike,
Actually i chose option A, as i didnt know "named for him" is a correct idiom.
Also , "equation named after him, to explain an airplane’s wing’s generation of lift", is n't an example of using inifinity of purpose?, did bernoulli derive the equation to explain the lift. Please help me eliminate option A.
