D Correct answer
Explanation

The law of diminishing marginal utility states that as consumption increases, total utility rises at a decreasing rate. When marginal utility reaches zero, total utility is at its maximum point - consuming one more unit would not increase satisfaction. Beyond this point, marginal utility becomes negative and total utility declines.

B Correct answer
Explanation

Some instructions require zero operands, such as NOP (No Operation), HLT (Halt), or RET (Return in some architectures). These instructions perform their function without needing to reference any data operands. Unary instructions need 1 operand, binary operations need 2 operands, and some complex instructions may need 3 operands, but 0 is the theoretical and practical minimum.

B Correct answer
Explanation

The regionMatches() method in Java's String class has two overloaded versions - one taking 4 arguments and another taking 5 arguments. The 5-argument version includes an additional boolean parameter to ignore case differences. Therefore, the maximum is 5 arguments.

A Correct answer
Explanation

A 16-bit signed integer uses one bit for sign, leaving 15 bits for magnitude. The maximum value is 2^15 - 1 = 32767. This is a standard limit in older C implementations with 16-bit ints.
