Determine the number of significant digits in the value 1001 .

Options

Correct answer

A. 4

Step-by-step solution

According to the rules of significant figures, all non-zero digits are significant. Zeros occurring between two non-zero digits are also considered significant. In the given value 1001 , the digits 1 and 1 are non-zero, and the two zeros are located between them. Thus, all four digits are significant. The number of significant digits is 4 .
