The disaster at Chernobyl caused the price of oil to:
increase.
change in an indeterminate direction.
remain the same.
decrease.
The disaster at Chernobyl in 1986 primarily affected the nuclear energy sector and had limited direct impact on the oil market. However, in the short term, there was a general increase in demand for oil as countries sought alternative energy sources due to safety concerns about nuclear power. This could lead to an increase in oil prices.
So, the most accurate answer would be: increase.
