There are two variable to analyze separately, 1) The incidence of light on the fungi, and 2) tTe incidence of temperature on the fungi's growth.
1) The incidence of light on the fungi. As seen on the sketch, both groups of fungi are pointing towards the light, from what it can be deduced that they "like" the presence of light.
2) The incidence of temperature on the fungi's growth. For this, there's a chart with quantitative information, where it can be seen that fungi that were left with more temperature (on the right) grew more than the ones that were exposed to lower temperatures (on the left). From this, it can be deduced that fungi prefer higher temperatures to grow more and faster.
Therefore, the correct answer is option C.
