Question

which one from the given options is not true for the ggollowing given code ?

[WebGet(UnTemplate = "Hello")]

String Sayhello();

1. "UnTemplate " property makes sayhello() indentified by "Hello" only

2. "UnTemplate " property kind of hides the Sayhello() operation

3. Sayhello() can be called only "GET" method of HTTP

4. But SayHello() can still be embedded directly in the uri/url
