Best answer
Right answer is (b) class name clashes

Best explanation: If modernizr’s class names are clashing with already existing class then we use classPrefix inside the configuration. It works same as hidden detects that adds .hidden class. Syntax is { “classPrefix”: “tee”, “feature-detects”: [“dom/hide”]}, this means instead of <html class=”hide”> we will get <html class=”tee-hidden”>.
