Which statement below is NOT a correct rule for determining significant digits? a All non-zero digits are significant b All zeros between non-zero digits are significant C Ending zeroes are significant if the decimal point is specified d Ending zeroes are always significant

Ending zeroes (also called trailing zeroes) are **only significant if a decimal point is specified**. For example:<br />- In 1200, the ending zeroes are **not significant** unless otherwise indicated (e.g., written as 1.200 × 10³ or 1200.).<br />- In 1200. or 1200.0, the ending zeroes **are significant** because the decimal point is explicitly shown.<br /><br />Thus, statement **d** is incorrect.
