A man has an antique pendulum clock of 1832 which bears the signature of the purchaser. He does not want to replace it in the fond memory of his great-grandparents. It ticks off one second in each side to side swing. It keeps correct time at `20^(@)C`. The pendulum shaft is made of steel and its mass can be ignored as compared to the mass of the bob. Linear expansion coefficient of steel is `1.2xx10^(-5@)C^(-1)`
How closely must the temperature be controlled so that it does not gain or lose more than a second in a day?

A

`pm0.2^(@)C`

B

`pm0.1^(@)C`

C

`pm1^(@)C`

D

`pm2^(@)C`
