"Is air pollution related to lichen growth?" What is a likely hypothesis for the question?

A. Air pollution must affect lichen growth.

B. No, air pollution does not affect lichen growth.

C. If air pollution is high, then lichen growth is high.

D. If air pollution is high, then lung disorder cases are high.​

If air pollution is high, then lichen growth is high.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

where are the choice options?
