Select the correct combination of mathematical signs to...

Given equation: 8 _ 27 _ 9 _ (6 \_5=0) Option 1) +, -, +, + Mathematical signs to sequentially place from left to right: ($$\begin{aligned} & \Rightarrow 8+27-9+6+5=0 \\ & \Rightarrow 46-9=0 \\ & \Rightarrow 37=0 \end{aligned}$$) Option 2),(+, \div,-,-) Mathematical signs to sequentially place from left to right: ($$\begin{aligned} & \Rightarrow 8+\underline{27 \div 9}-6-5=0 \\ & \Rightarrow \underline{8+3}-6-5=0 \\ & \Rightarrow 11 \underline{-6-5}=0 \\ & \Rightarrow \underline{11-11}=0 \\ & \Rightarrow 0=0 \end{aligned}$$) Option 3),(- ,\div,+,+) Mathematical signs to sequentially place from left to right: ($$\begin{aligned} & \Rightarrow 8-\underline{27 \div 9}+6+5=0 \\ & \Rightarrow \underline{8}-3+6+5=0 \\ & \Rightarrow \underline{19-3}=0 \\ & \Rightarrow 16=0 \end{aligned}$$) Option 4),(-,+, \div,+) Mathematical signs to sequentially place from left to right: ($$\begin{aligned} & \Rightarrow 8-27+9 \div 6+5=0 \\ & \Rightarrow \underline{8}-27+1.5+5=0 \\ & \Rightarrow \underline{14.5-27}=0 \\ & \Rightarrow-12.5=0 \end{aligned}$$) Hence, the correct answer is ",(+, \div,-,-) ".
