The techniques of multiple correlation and regression can be used if each independent variable is linearly related to the dependent variable. The other options are incorrect: there is no limit to the number of variables that can be included; the independents should not be strongly correlated with each other as this violates the assumption of independence; and there is no rule that the sample size must be less than 100 although having an adequate sample size is important.
