Range C$2$:C$200$ contains sales values and range A$2$:A$200$ locations $($Boston$,$ New York City, London, $...).$ What would be an appropriate formula to calculate the total sales for all orders originating from Boston

$$ a$)=$ COUNTIF$($C$2$:C$200,$ A$2$:A$200,$ "Boston"$)$

b$)=$ SUMIFS$($C$2$:C$200,$ A$2$:A$200,$ "Boston"$)$

c$)=$ SUMIF$($C$2$:C$200,$ A$2$:A$200,$ "Boston"$)$

$$ d$)=$ COUNTIFS$($C$2$:C$200,$ A$2$:A$200,$ "Boston"$)$
