The given quantity has 4 significant figures, so we need to express the answer with 4 significant figures. The numerical value of the given expression is approximately 0.2926, which can be rounded to 0.293. This value can be expressed in scientific notation as 2.93 x 10^-1 or 0.293 x 10^0. To express this value with 4 significant figures in scientific notation, we need to move the decimal point 2 places to the right, and write the result as 2.93 x 10^-3. This can be written in the required format as 6.00 x 10^-3, which corresponds to option C. Options A, B, and D are not correct because they do not have the correct number of significant figures or they do not express the value in scientific notation with the correct exponent.
