The correct answer to this open question is the following.
Although the question does not provide options, we can answer the following.
The groups that successfully lobbied the governor of Texas in 2013 over a bill that would have allowed employees alleging they had been subject to wage discrimination to sue their employers in court were "those groups that were representing the interests of employers or owners of businesses."
In United States politics there is a figure called PAC's or Political Action Committees that collects money to support political candidates in campaigns and exert too much influence in the victory or defeat of a candidate.
These interest groups raise a lot of money to support their personal agendas and try to influence legislators' decision to pass or not -according to their interests- the kind of legislation that affects them. That was what happened in the above-mentioned case when the groups successfully lobbied the governor of Texas in 2013.
