To calculate the return, we need to use the formula: 
Return = (Today’s Price – Yesterday’s Price) / Yesterday’s Price * 100

Today’s Price = 12,743.40 
Yesterday’s Price = 12,980.84 (since we are measuring the return from the previous day’s close)

Return = (12,743.40 - 12,980.84) / 12,980.84 * 100 = -1.83%

Therefore, the answer is C, -1.83 percent.
