Answer:
- "To find good players, he scouted women’s softball clubs, which were very popular at that time."
Step-by-step explanation:
The last choice makes it seem like he's solitary exploring the famous ladies' softball clubs as opposed to every one of them.
The second to last alternative isn't syntactically right a result of the comma among explored and women's.
The second choice just replaces the period with a comma and, which makes despite everything it appear as though the two snippets of data are isolated.
So "To find good players, he scouted women’s softball clubs, which were very popular at that time" is the right choice.
