(B) Let the percentage abundance of $C^{12}$ be $x\%$ and that of $C^{13}$ be $(100-x)\%$.The average atomic mass is given by the formula:$\text{Average Atomic Mass} = \frac{(x \times 12) + ((100 - x) \times 13)}{100}$Substituting the given values:$12.011 = \frac{12x + 1300 - 13x}{100}$$12.011 = \frac{1300 - x}{100}$$1201.1 = 1300 - x$$x = 1300 - 1201.1$$x = 98.9\%$Therefore,the abundance of $C^{12}$ is $98.9\%$.
