Right answer is (c) Keeping of pattern at too low temperature

To explain: When the mercury is used in place of wax as a pattern material, it has an advantage that it does not expand when changed from solid to liquid state as wax. But the main disadvantage or drawback is keeping the pattern at such low temperature, which is mainly responsible for its less useful.
