How to become more confident around horses
Watch horses from afar.
Though there are exceptions, most horses are fairly calm and docile when left to themselves. Watching a herd of horses feed in a field a short distance away from you can make them seem much less intimidating than they might otherwise.

OPT:
(A). Try to observe them from a distance while knowing they are not a threat, as horses can perceive and react to things that they normally would not, and can tell what they are feeling even when alone. Watch a herd of horses somewhere in the desert..
(B). These horses are also less tough and more relaxed and will naturally stay a little longer after engaging in a walk. There's nothing you can do to cut down on your urge to take a close look from a distance..
(C). Do not try to pet or restrain a horse when they're not seen. The feeling of control and power comes naturally to horses and you do not need to worry about disrupting this impression..
(D). Once you're comfortable with this, you can gradually start interacting with horses close up. Use this opportunity to observe horse body language..
The answer is:
(D).
