Answer:
A. meet with representatives to educate them about the bill
Step-by-step explanation:
An interest group can be defined as a group of people sharing common aims, ideas and concerns, which seeks to influence government or a public policy.
This ultimately implies that, the interest groups consists of individuals who are only concerned about influencing public policy of the government on the basis of a particular common aim and interest.
Hence, an action which a special interest group would take in order to gain support for a law proposed in Congress is meeting with representatives to educate them about the bill. This would help the interest group to have a better understanding of the bill, as well as endearing them to the representatives.
A bill can be defined as a formally written proposal presented to the legislators such as senators or house of members for legislation.
