Significant figures in 3.1205

Explanation:

Significant figures refer to the number of digits in a number that are reliable and meaningful. To determine the number of significant figures in a number, we need to follow certain rules:

1. Non-zero digits are always significant. In 3.1205, all digits except for the leading zero are non-zero, so we count all of them as significant.

2. Leading zeros are not significant. In 3.1205, the first digit is a zero, which is a leading zero. Therefore, it is not considered significant.

3. Trailing zeros are significant only if the number contains a decimal point. In 3.1205, the last digit is a five, and there is a decimal point, so we count it as significant.

Based on these rules, we can count the number of significant figures in 3.1205 as follows:

3 non-zero digits (1, 2, 0)
1 significant trailing zero (5)
Total: 4 significant figures

Therefore, the correct answer is option 'D', which states that there are 5 significant figures in 3.1205.
