Right option is (b) 7 For explanation I would say: The prototype is an object that is associated with every functions and objects by default in JavaScript, where function’s prototype property is accessible and modifiable and object’s prototype property (aka attribute) is not visible. There are a total of 7 properties in the prototype object namely: perceivedTime redirectTime cacheTime dnsLookupTime tcpConnectionTime roundTripTime pageRenderTime.
