The correct statement about a long integer is: It uses more than 32 bits.
A long integer typically refers to a data type that can represent larger integers than the standard int data type, which is usually 32 bits in many programming languages. A long integer often uses 64 bits, depending on the language and system architecture. The other statements are incorrect for describing a long integer:
- "It has a maximum of 17 bits." is false because long integers can have more than 17 bits.
- "It has a decimal." is misleading because integers, including long integers, do not have a decimal (they are whole numbers).
- "It uses only 1s and 0s." while true in a binary representation sense, does not specifically describe the nature of a "long integer" uniquely compared to other data types.
Thus, the first statement is the most accurate in this context.
