Answer

Explanation:

Step1: Recall significant - figures rules

Non - zero digits are always significant. Trailing zeros in a number without a decimal point may or may not be significant. In scientific notation, all digits in the coefficient are significant.

Step2: Analyze option A

For 11,890, there are 5 non - zero digits. So, it has 5 significant figures.

Step3: Analyze option B

For 750, the trailing zero is not significant (since there is no decimal point). So, it has 2 significant figures (7 and 5).

Step4: Analyze option C

For 320,050, the non - zero digits 3, 2, and 5 are significant, and the zero between 2 and 5 is significant. So, it has 5 significant figures.

Step5: Analyze option D

For $10.4\times10^{5}$, the coefficient 10.4 has 3 significant figures (1, 0, and 4).

Answer:

B. 750
