Which detail from the passage BEST supports Rainsford's survival skills?

A. Rainsford had dug himself in in France when a second's delay meant death. That had
been a placid pastime
compared to his digging now. The pit grew deeper.

B. Rainsford, crouching there, could not see the general, nor could he see the pit. He lived
a year in a minute. Then he felt an impulse to cry aloud with joy.

C. He knew his pursuer was coming; he heard the padding sound of feet on the soft earth,
and the night breeze brought him the perfume of the general's cigarette.

D. Then, as he stepped forward, his foot sank into the ooze. He tried to wrench it back,
but the muck sucked viciously at his foot as if it were a giant leech.
