There Is a Giant Sequoia (Sequoiadendron Giganteum) Named Washington (After

There is a giant sequoia (Sequoiadendron giganteum) named Washington (after George Washington) that was believed to be the second largest tree in the world (253.7 ft. in height!) until it was struck by lightning in 2003. The lightning strike caused a fire at the top of the tree that reduced Washington's height to about 229 feet. Carbon released from the tree due to that fire could have:

A) been incorporated into the wood of a nearby sequoia through the process of photosynthesis.
B) been incorporated into the wood of a nearby sequoia through the process of cellular respiration.
C) been incorporated into the cells of a human through the process of cellular respiration.
D) traveled through the atmosphere and eventually dissolved into the ocean.
