Three federal lawsuits that charge a prominent investment firm with releasing fraudulent financial reports to promote sales of its mutual funds and raising disturbing questions about how to control fraudulent behavior in the financial services industry, behavior that appears to be on the rise.

(A) that charge a prominent investment firm with releasing fraudulent financial reports to promote sales of its mutual funds and raising disturbing questions about how to control fraudulent behavior in the financial services industry, behavior that appears to be on the rise

nothing in parallel to and raising
no verb for lawsuits

(B) charging a prominent investment firm with releasing fraudulent financial reports and promoting sales of its mutual funds raises disturbing questions about how to control fraudulent behavior in the financial services industry that appears to be on the rise
subject verb agreement error

(C) that charge a prominent investment firm with releasing fraudulent financial reports to promote sales of its mutual funds raises disturbing questions about how to control fraudulent behavior in the financial services industry, which appears to be on the rise
subject verb agreement error

(D) charge a prominent investment firm with releasing fraudulent financial reports to promote sales of its mutual funds raise disturbing questions about how to control fraudulent behavior in the financial services industry that appears to be on the rise

two verbs running into each other

(E) charging a prominent investment firm with releasing fraudulent financial reports to promote sales of its mutual funds raise disturbing questions about how to control fraudulent behavior in the financial services industry, behavior that appears to be on the rise

correct verb


So on subject verb itself we were able to tackle the long question
