The correct options are as follows:
A. There are many regulations which have been put in place by the government in order to allow entrepreneurs to obtain credit and capital.One of such regulation is Equal Credit Opportunity Act. This law was enacted in USA in October, 1974 in order to pave way for business individuals to obtain loans. The law makes it illegal for any creditor to discriminate against any credit applicant on the basis of color, race, religion, etc.

B.The full sentence is this:
People who want to obtain CREDIT from financial institutions can used their PROPERTY rights to do so.
Credit as used in this context refers to loan, which one want to use to carry out a particular business activity. Such loans are usually obtained from commercial banks and other credit facilities. Individuals that are borrowing in this manner have to pay interest on the loans that are been given to them.

Property right refers to the legal ownership of a particular property. Some banks and creditors usually require that loan applicants should use their properties as guarantee that they are going to repay the money they are borrowing. In case they are not able to repay the money, their properties will be sold and the money used to replace the one they borrow.

I'll go in reverse order, as I want to explain more with question #1.

For question #2:
People who want to obtain credit from financial institutions can use their property rights to do so.

For question #1: Entrepreneurs need to be able to borrow funds without being subject to discrimination, and they need an economic environment open to investment in new businesses.  

The  Equal Credit Opportunity Act (1974) established that lenders cannot discriminate against any credit applicant on the basis of color, race, religion, etc.  This protects entrepreneurs from discriminatory lending practices.

The Jumpstart Our Business Startups Act, or JOBS Act (2012), aimed to create an open environment for new businesses by entrepreneurs, by relaxing some of the securities regulations on small businesses. Title II of that act allows entrepreneurs to communicate with a larger number of investors as they sought funding. Title III (with rules that went into effect in 2015) allows for crowdfunding.  Title IV allows investors to invest up to ten times as much in startups, with less strenuous registration requirements.
