Anyone can start a business without 200 USD capital.
One option is consignment. When I was still a student, I ask the administrator in our canteen if she could let me sell healthy products and share the 10% profit. Next day during lunch break, I ask one small business owner in my hometown that manufacture peanut products if I could sell their products in our school canteen. The owner agreed and give me big discount.. After that, I go back in our school carrying 2 large plastic bags inside are peanut products. Every week, as agreed upon, I give the 10% profit to the school canteen, pay the business owner and get products refill. The canteen staff do the selling while I'm studying.
Another option is direct selling. When I was walking going home after school, I see a poster about income opportunity seminar that will happen in Saturday in their office. I attend that seminar and they give me brochures inside different selection of shoes, pants, etc. made in our country. They told me that if someone I referred bought or also like to sell those kind of products, I will get a commission.
There are still many option that anyone can start a business without capital like create a Youtube video and put a link of product from online marketplace like Amazon. When someone click that link and decided to buy, you will get commission.. Another is sell the consign products or products in the brochures I've said before in Facebook.
Going back to your question what business you can start if you have only 200 USD capital, I will only share those business that I personally try, Using 200 USD capital, you can sell prepaid load credits, accept bills payments, and send money to other in Coins.ph, Another is selling ice candy in your house. To make ice candy, make a juice, put the juice in small long plastic, and put in inside the freezer. Once it become solid, you can sell it. Another one is ask a school if you can put a printing business. To put a printing business, buy a printer, short and long bond paper, and use your laptop.
