Answer: C
Reasoning: Match merging will merge several data sets together
based on the value of a common variable. Interweaving can do the
same as match-weaving, but with more than one common variable.
Concatenation will append, or add on, to existing data sets.
interleaving method does not merge obervations like match-maergin method. it is almost like concatenation.
the only difference between interleaving and concatenation is that interleaving sorts the observations by the specified variable.
Isn't Append the right choice .. Match merge doesn't right to the base dataset .. hence D
