Option 1 -

Both A and R are true and R is the correct explanation of A

Option 2 -

A is false but R is false

Option 3 -

A is true but R is false

Option 4 -

According to question, we can write

$d = d_{0} (1 + α Δ T) \Rightarrow 6.241 = 6.230 (1 + 1.4 \times 1 0^{- 5} \times Δ T)$

$\Rightarrow T = 126.18 + 27 = 153.18 ° C$
