Drop manholes are typically characterized by the absence of entry ladders and covers, having depths greater than 3.5 meters, and featuring drains at various levels. They serve specific purposes in drainage systems and infrastructure, often designed for managing water flow efficiently and safely.

ANS:A - 0.15

The refrigeration capacity of a household refrigerator is typically around 0.15 tons. Household refrigerators are usually small-scale refrigeration systems designed for domestic use. Their cooling capacities are measured in tons of refrigeration (TR), where 1 ton of refrigeration is equal to the cooling capacity provided by the melting of 1 ton of ice in 24 hours, which is approximately equal to 12,000 BTU/hr. Given that household refrigerators are small and not intended for heavy-duty cooling like commercial or industrial refrigeration systems, their capacities are typically much lower. A typical household refrigerator might have a capacity ranging from 0.1 to 0.2 tons, with 0.15 tons being a common value. Therefore, the closest option to this would be 0.15 tons.
