D Correct answer
Explanation

When joining n heterogeneous sources in Informatica, you need n-1 Joiner transformations. For 5 sources, you need 4 Joiners. Joiner can only join two sources at a time, so you chain them: source1+source2 → output1, output1+source3 → output2, output2+source4 → output3, output3+source5 → final output.
