What Global API Data-Sizing convention flag prevents an API request from propagating to further requests when provided as a Boolean parameter with a value of true?
A . ccrz.ccAPI.SZ_REL
B . ccrz.ccAPI.SZ_ASSC
C . ccrz.ccAPISizing.ASSC
D . ccrz.ccAPISizing.REL

Answer: B

Explanation:

The Global API Data-Sizing convention flag that prevents an API request from propagating to further requests when provided as a Boolean parameter with a value of true is ccrz.ccAPI.SZ_ASSC. This flag indicates that only one API request should be executed with the specified sizing block, and any subsequent requests should use their own default sizing blocks. For example, ccrz.ccServiceCart.getCart(ccrz.ccAPI.SZ_L,true) will use the SZ_L sizing block for retrieving the cart data, but any other requests that are triggered by this method will use their own default sizing blocks.
