(D) The given value is $4.700 \,m$.According to the rules for significant figures,trailing zeros in a number with a decimal point are significant.Therefore,$4.700$ has $4$ significant figures.Now,let us check the options:$(a)$ $4700$: Trailing zeros without a decimal point are not significant. It has $2$ significant figures.$(b)$ $0.047$: Leading zeros are not significant. It has $2$ significant figures.$(c)$ $4070$: Trailing zeros without a decimal point are not significant. It has $3$ significant figures.$(d)$ $470.0$: Trailing zeros in a number with a decimal point are significant. It has $4$ significant figures.Thus,the value $470.0 \,m$ has the same number of significant figures as $4.700 \,m$.
