What Is the Difference Between Multinomial Logit and Conditional Logit

What is the difference between multinomial logit and conditional logit?

A) conditional logit allows for variables to vary by individual and choice while multinomial logit only allows them to vary by individual
B) multinomial logit allow for 3+ choices,conditional logit only accommodates 2
C) multinomial logit is estimated with least squares,conditional logit by maximum likelihood
D) multinomial logit has different coefficients for each choice equation,conditional logit has equal coefficients across choice equations on common variables
