Explanation:

• (a) Temperature has no true zero (0 degrees Celsius doesn't mean absence of heat), so it's interval.
• (b) Time since last visit has a true zero (0 time means no time has passed since last visit), so it's ratio.
• (c) Happiness level on a 0 - 10 scale has an order but differences may not be meaningful in a strict numerical sense, so it's ordinal.
• (d) Marital status is a category (e.g., single, married etc.) with no order or numerical value, so it's nominal.

Answer:

(a) Interval
(b) Ratio
(c) Ordinal
(d) Nominal
