Answer:
b. Standard and Poor s and Moody
Step-by-step explanation:
Standard and Poor's and Moody's are rating agencies that measure the investment risks of companies and countries. For this, these agencies evaluate the quality of securities and the financial health of a company or country. These agencies then determine an investment seal, which is a way of ranking which institutions or countries are most reliable to invest in and which are the most risky, and publish it so that economic agents have information to base their decisions on.
