Answer:
It will lead to an increase in consumption of good X only if X is a normal good ( D )
Explanation:
If consumer has rational, monotonic and convex preference the decrease in price of good X will lead to an increase in consumption of good X only if X is a Normal good .
This is because the demand for Normal goods increases with increase in consumers income. therefore a decrease in price will automatically lead to an increase in demand because of the increase in the purchasing power of the consumer's income.
