The correct answer is option 3, which states that committees 1, 2, and 3 submitted reports on Electoral reforms.

Let`s analyze each option to understand why option 3 is correct:

Option 1: This option states that committees 1, 3, and 4 submitted reports on Electoral reforms. Option 1 is incorrect because it includes committee 4, which did not submit a report on Electoral reforms.

Option 2: This option states that committees 2 and 4 submitted reports on Electoral reforms. Option 2 is incorrect because it does not include committee 1, which did submit a report on Electoral reforms.

Option 3: The correct option states that committees 1, 2, and 3 submitted reports on Electoral reforms. This is the correct answer as it includes all the committees that submitted reports on Electoral reforms.

Option 4: This option states that committees 3 and 4 only submitted reports on Electoral reforms. This option is incorrect because it does not include committee 1, which also submitted a report on Electoral reforms.

Therefore, the correct option is option 3, as it includes all the committees that submitted reports on Electoral reforms.
