Plant will show normal photosynthesis

(C) The atmospheric concentration of $CO_2$ is approximately $0.03\%$ to $0.04\%$,which is equivalent to $300-400 \, ppm$. Since $300 \, ppm$ is the ambient level of $CO_2$ in the atmosphere,the plant will perform photosynthesis at its normal,baseline rate. Therefore,the correct option is $(c)$.
