Explanation:

Step1: Recall significant figure rules

Significant figures rules: Non - zero digits are significant. Zeros between non - zero digits are significant. Trailing zeros in a decimal number are significant.

Step2: Analyze the number 1.050

• The digit 1 is a non - zero digit, so it is significant.
• The zero between 1 and 5 is a zero between non - zero digits, so it is significant.
• The digit 5 is a non - zero digit, so it is significant.
• The trailing zero after 5 (in the decimal part) is significant.

Counting these significant figures: 1, 0, 5, 0. So there are 4 significant figures.

Answer:

d. 4
