A researcher wishes to study the effects of a concentrated remedial reading program on the reading achievement of disadvantaged children.

What would be the most effective way for the researcher to control these variables?
 
  a. Set up groups and then check to make sure that there are no significant differences between the groups on intelligence and reading pretest scores.
  b. Randomly assign children to experimental and control groups.
  c. Match the children on intelligence test and reading pretest scores and then randomly assign the matched pairs to experimental and control groups.
  d. Randomly assign children to experimental and control groups and use intelligence test and reading pretest scores in an analysis of covariance.
