The right answer is A.
Since matter is generally composed of several pure bodies (chemical compounds and simple bodies), the chemical composition of a product furnishes the quantity or proportion of each of the pure substances which compose it; they are generically called components.
For answer B it is rather the definition of a chemical structure, it refers to both its molecular topology, its geometry (molecular geometry or space group for a crystal) and its electronic structure.

On March 24, 1989, the oil truck Exxon Valdez reached Alaska's Prince William Sound, after leaving the Valdez Marine Terminal full of crude oil. At 12:04 am, the ship uncovered a reef, ripping open the hull and discharging nearly 10 million gallons of oil into the atmosphere. Initial acknowledgments by Exxon and the Alyeska Pipeline Company were inadequate to accommodate much of the spill, and a hurricane swept in soon after, spreading the oil extensively.
Eventually, more than 1,000 miles of coastline were polluted, and hundreds of thousands of species of plants and animals died damaging the marine life to the greatest extent.
The Exxon Valdez spilled more than 10 MILLION gallons of oil into the Prince William Sound, damaging marine life.
An example of "DNA overload" occurs when the replication system has trouble keeping up with the demand for DNA replication. This can occur when there is a high rate of replication initiation, which induces the rapid development of multiple replication forks.
For efficient and timely replication, the replication process requires coordination among many proteins and enzymes in its many complex steps. When too many replication forks form rapidly and overwhelm the replication machinery, replication mistakes, fork stalling and perhaps DNA damage can occur.
