None of the above

Detailed explanation-1: -The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second. The higher the clock speed a CPU has, the faster it can process instructions.
Detailed explanation-2: -Clock speed is rather a count of the number of cycles the processor goes through in the space of a second, so as long as all cores are running at the same speed, the speed of each clock cycle stays the same no matter how many cores exist.
Detailed explanation-3: -One gigahertz represents 1 billion cycles per second. Clock speed, which is also measured in hertz, refers to synchronous circuit clock frequency, for example, a CPU. One clock cycle lasts only 1 nanosecond and toggles between 0 and 1.
Detailed explanation-4: -The CPU multiplier (sometimes called the “CPU ratio”) is multiplied against the CPU Base Clock (or BCLK) to determine the processor’s clock speed. A CPU multiplier of 46 and a base clock of 100 MHz, for example, results in a clock speed of 4.6GHz.
