Doubts: Mock by HFSJ 1st Edt

Given that a deployment descriptor has only one security role, defined as:

<security-role>
<role-name>Member</role-name>
</security-role>

Which are valid <auth-constraint> elements that will allow users to
access resources constrained by the security role declared?
(Choose all that apply.)

A. <auth-constraint/>
B. <auth-constriant>*</auth-constraint>
C. <auth-constraint>Member</auth-constraint>D. <auth-constraint>MEMBER</auth-constraint>
E. <auth-constraint>”Member”</auth-constraint>

Given answers B, C

I am agree with the option C, but i haven't notive option B anywhere in the book. Is this gives the same effect if we say ???
<auth-constriant>
<role-name>*<role-name>
</auth-constraint>

Please correct me

No, its there in book with examples . I am in office , cant tell you page number sorry .

See * means all are allowed to access.

I also used to get confused , then i summerized in this

Hope , it will clear your doubt.

Thanks Vishal.

Yes,

HFSJ 1st edition :
