Pardon My Ignorance, Couple of Questions

[Alohaed]

A) A French golfer on the Euro' Challenge Tour was DQ'd for running out of balls. Is there a max limit to how many balls a player can have, or did he simply not have enough?

B) When watching the tour each week, the commentator most of the time tells us what club a player is using for the shot. I can see if it's a driver or wood, yet irons? Does someone by the player(caddie, etc), signal which club is being used?

C)

No max, and he could have borrowed one from someone else, but that's a two-stroke penalty if the one-ball rule is in effect.

They use hand signals. A 4 pointed upward is a 4-iron, pointed downward is a 9-iron (4+5 fingers).

Interesting, I didn't know that they used the downturned hand to add 5.  How do they differentiate each wedge?

I don't know. Closed fist is usually a pitching wedge (i.e. "10").
