Concept:Rounding to the nearest tenth means keeping only one digit after the decimal point.Explanation:Write the given number as $134.78$.Here, the tenths digit is $7$ and the hundredths digit is $8$.When rounding, look at the digit immediately to the right of the digit being rounded.That digit is the hundredths digit $8$.Since $8$ is greater than or equal to $5$, we increase the tenths digit $7$ by $1$.So, $7$ becomes $8$.All digits after the tenths place are then removed.Therefore, $134.78$ rounded to the nearest tenth is $134.8$.Among the given options, this matches $134.8$.Answer:$134.8$ (Option C)
