This question is based on the following passage. i was in the national forest with my camera. the day was crisp, and the leaves were turning gold and red. when i spotted the white-tailed buck, i froze. he wasn't more than 15 yards from where i was standing. the wind must have been right, because he kept on browsing the mossy ground. i lifted my camera very slowly. carefully, holding my breath, i lifted the camera to my eye. turning the focus ring, i framed the deer's head. just as i was ready to press the shutter release, the buck raised his head. he was looking my way with wide eyes. click. i took the picture. an instant later, the deer bounded away into the forest. he took off, but i had the shot. today, the framed photo of that buck hangs above our fireplace. what is the author implying in the phrase "the wind must have been right"? a. the deer was not able to pick up the scent of the author.
b. the author was fortunate to have his camera with him.
c. the deer was clearly not afraid of humans.
d. the author was worried the wind would disturb his shot.
