Answer 1

Try with below code.

<% user = User.find(1) %>
<% case user.role %>
<% when "A" %>
  <%= link_to "Profile", "YOUR URL" %>
<% when "B" %>
  <%= link_to "Profile", "YOUR URL" %>
<% when "C" %>
  <%= link_to "Profile", "YOUR URL" %>
<% else %>
  <%= link_to "Profile", "YOUR URL" %>
<% end %>

One, more thing it's not good to write this code into view file. rails provide helper method to write your business logic for view file.

In user helper

 def role_link(user)
  case user.role
    when 'A'
      url = 'redirect_url'
    when 'B'
      url = 'redirect_url'
    when 'C' 
      url = 'redirect_url'
  else
    url = 'redirect_url'
  end
  url
end

In view file

  <%= link_to 'profile', role_link(User.find(1) %>
